数据结构c语言期末考试题库及详解答案数据结构C语言期末考试题库及详解答案一、选择题1. 在数据结构中,线性表的顺序存储结构被称为:A. 链式存储结构B. 栈C. 队列D. 数组答案:D2. 下列关于栈的描述,错误的是:A. 栈是一种特殊的线性表B. 栈的特点是后进先出C. 栈顶元素是最后插入的元素D. 栈的插入和删除操作都发生在栈顶答案:C二、填空题1. 在C语言中,定义一个具有10个元素的整型数组可以使用语句:________。
答案:int arr[10];2. 链表与数组相比,其优点是________。
答案:动态内存分配,不需要预先知道数据规模三、简答题1. 简述二叉树的遍历方法有哪些,并说明它们的特点。
答案:二叉树的遍历方法主要有前序遍历、中序遍历和后序遍历三种。
前序遍历首先访问根节点,然后递归地遍历左子树和右子树;中序遍历首先遍历左子树,然后访问根节点,最后遍历右子树;后序遍历首先遍历左子树和右子树,最后访问根节点。
每种遍历方法都可以用来对二叉树进行不同的操作和分析。
2. 什么是哈希表?它在实际应用中有哪些优点?答案:哈希表是一种通过哈希函数将键映射到表中一个位置来访问记录的数据结构。
它的优点包括:快速的数据访问速度,因为哈希表通常在常数时间内完成查找;动态的内存分配,可以根据需要调整存储空间;以及灵活的键值对存储方式。
四、编程题1. 编写一个C语言函数,实现单链表的逆序输出。
答案:```c#include <stdio.h>#include <stdlib.h>typedef struct Node {int data;struct Node *next;} Node;void reversePrint(Node *head) {if (head == NULL) return;reversePrint(head->next);printf("%d ", head->data);}int main() {Node *head = (Node *)malloc(sizeof(Node));head->data = 1;head->next = NULL;// 假设链表已经构建完毕reversePrint(head);return 0;}```2. 请实现一个C语言函数,用于计算一个字符串中不同字符的数量。

Almost 68% of people think that the government has secret knowledge of extraterrestrial life. It is not (47) _surprising__ (surprise) that the government has come under more and more (48) pressure____ to declassify its UFO records and make them public. A variety of different groups have been involved in these efforts.One group to become involved is called CFI, the Coalition for Freedom of Information, John Podesta, who was White House Chief of Staff during Bill Clinton’s (49)presidency____(president), is one of the many high-powered people active in this group. CFI’s aim is not to prove the (50) _existence___(exist) of extraterrestrial life, but to make it easier for scientists in general to study unexplained aerial phenomena. Podesta and his group has asked the Pentagon to declassify its UFO records and therefore provide scientists (51) with____ data that will help in the study of UFOs.CFI has requested the release of information on several UFO cases, starting with the Kecksburg, Pennsylvania, incident. This incident took (52) __place__ in 1965 when a large acorn-shaped object, the size of a small car, crashed in Pennsylvania.

Officials explained that nothing was found or recovered and that maybe the fireball in the sky was a meteor. But many witnesses say they saw a number of military personnel from the Army and the Air Force search the woods, and later that evening, saw a large militarytractor-trailer coming from the area carrying a large object under a tarp.Part IV Reading Comprehension (40 marks)Read the following passage. Each passage is followed by several questions. Respond to the questions using information from the passage. Remember to write the answers on the answer sheet.Section A (10 marks)Questions 56-60 are based on the following passage.The average automatic teller machine (ATM) is not very smart. It will give money to anyone who has the right card and punches four or five keys in the right order. Some analysts estimate that as many as 30% of ATM transaction worldwide are cases of theft. To increase security at cash machines, some banks have tried to make their ATMs a little smarter. A small camera on the machine looks directly into the eye of every customer. It scans one iris and compares the tiny patterns of ridges, dots, and other features to a code in its computer. If there is a match, the ATM will start counting out cash. If not, a message is automatically sent to the nearest police station.Iris-scanning is one fast-growing form of biometric identification --- determining who someone is by examining features the body. One of the earliest biometric techniques was fingerprinting. The line on fingerprints are unique to each person, so not even identical twins have the same fingerprints. Fingerprinting has become famous as a way of finding out who committed a crime, but it very often fails. A careful criminal can swear gloves, avoid touching thing, or even alter his fingerprints by burning, cutting, or scraping them. In the search for a more reliable system, security experts have focused on the eye.Like a fingerprint, every iris is, for all practical purposes, unique. Each person’s right iris is even different from his or her left one. A low-cost digital camera, like the kind installed at ATM machines, can easily detect hundreds of different features in the iris. The chance of two irises having the same features is close to zero. Tests have shown that iris-scanners are very hard to fool. They can tell the difference between a real iris and a false one. They can see right through colored contact lenses, eyeglasses, and even mirrored sunglasses. Although many criminal are willing to burn or cut their fingers in pursuit of the perfect crime, few would be willing or able to alter their irises.T o make iris-scanning work, a computerized database has to match certain iris features with certain people. This means that each A TM customer has to allow a bank to photograph his or her iris and keep that highly personal information in a computer. Some people have worried, however, that an increased use of iris-scanning will lead to a dangerous loss of privacy. By mountingiris-scan cameras in public places, governments could track a private citizen all day long without the person’s knowledge. This would be a great advantage to the police, but it could also give corrupt officials a new way to control their opponents. The military’s development of tiny robots suggests that government iris-scanners could even invade private homes!Questions 56-60Complete the summary with words from the passage, changing the form where necessary, with only one word for each blank.Section B (10 marks)Questions 61-65 are based on the following passage.Seed catalogues feature hundreds of flowering species. For the persons just beginning garden this can be bewildering, and below are the details of some popular choices, nearly all of which should be sown in the spring. With the exception of busy lizzies, which need a little care, they are all very easy to grow from seed.DahliasThese are sturdy plants bearing showy flowers in a wide range of rather gaudy colors. Sow in a frame in April and plant the seedlings out when frosts are over. Dahlias flower throughout the summer and into the autumn. When autumn frosts begin to make them look unhappy, you should dig up the tuberous roots and save them. A frost-free loft, shed or garage is the ideal place. The following spring you plant the tubers instead of sowing seed again.LupinsLupins are hardy perennials. This means that the plants will stay in your garden and carry on flowering year after year. Seed sown in April will usually give you some spikes of colors in the first summer, and year by year the plants get bigger and the flowering stems get taller and grander. Selective breeding has led to the introduction of some fine, bicolored varieties in some dazzling shades. The short-lived flowers make a real misunderstanding spectacle.Busy lizziesLike dahlias, busy lizzies need to be started offunder glass, as they cannot stand frost, and pantingout is best done in May. Outdoor flowering ends inSeptember, so beat the frosts and bring your favoritespecimens indoors to give your home some sintercolor! Indoors they will carry on floweringindefinitely, though you may like to plant them outagain when spring returns. Like pansies (below) they do very well in sun or shade, but the soil must be moist. Most varieties grow to be a height of only 20 cm or so.PotentillasPotentillas are hardy shrubs. In other words, the woody branches spring from groundlevel —there is no central trunk. Seed is probably best sown in autumn, in which case you should keep the plants in a sheltered spot until April offers favorable conditions for planting out. Once flowering begins in early summer the best varieties (such as Melton Fire) will stay in bloomATM transactions are often cases of theft, where an unauthorized user takes (56) __money_. To decrease insecurity, some banks have installed iris-scanning machines at ATMs. These small cameras scan the user’s iris, recording its features and (57) _comping___ them to a digital file. Every person has a (58) _ unique ___ iris, making iris identification highly reliable. Earlier efforts at biometric identification often relied on fingerprints. However, fingerprints can easily be (59) altered____ through cutting, burning or scrapping. Iris scanners are so effective that they can even see through contact lenses and mirrored sunglasses. Use of iris scanners would provide great advantages to the police. However,others worry about a loss of (60) ____.almost ceaselessly for years on end while at the same time spreading out to provide ground cover or a low hedge.PansiesPansies have a good long flowering season year after year, and some varieties can be sown in spring to give truly splendid results the first autumn. Unlike dahlias and lupins, which can easily grow a meter tall, pansies grow no higher than 10 or 20 cm. Their soil, position and moisture requirements are just like those of busy lizzies but pansies differ in being hardy. Give them a try!Questions 61-63Decide whether the following statements are true (T) or false (F) according to the passage.61. Both dahlias and lupins, which are sown in April, need protecting from frost.62. Brought indoors in autumn, dahlias, busy lizzies and potentillas will carry on flowering almost non-stop.63. Among all the flowers busy lizzies are not very easy to grow from seed.Section C (10 marks)Questions 66-70 are based on the following passage.When looking for love, people may go to some extreme lengths. They might go on blind dates set up by family and friends. They might write personal ads to place in newspapers. Or they might use a computer to help them in their search for a soul mate by joining an online dating services. Some people have even tried to find their perfect match through game shows on television. Many of these TV dating shows, including The Bachelor and Who Wants to Marry a Millionaire? have proved to be ratings blockbusters, with millions of viewers watching each week to find out which of the contestants will find true love.Of all these game shows, perhaps the one with the most unexpected ending was Mr. Right, which was shown in England in 2002. On the show, a bachelor, thirty-five-year-old Lance Gerrard-Wright, dated fifteen women to find the one who was his ideal partner. The host of the show was Ulrika Johnson, an English celerity originally from Sweden. For seven weeks on the show, Gerrard-Wright took turns going on dates with each of the women, taking them to expensive restaurants and exotic locations. He even met the women’s families and introduced them to his own. Then at the end of each episode, he would choose between one and three of the contestants with whom he had felt the least compatible, and say goodbye to them.At one point during the series, one contestant volunteered to leave because she said she didn’t find him attractive. After two dates she said she had had en ough, and she couldn’t see it working. ―He wasn’t my cup of tea.‖ In another episode the woman he was on a date with burst into tears when he called her by another contestant’s name. ―You called me by another girl’s name. I can’t believe you did that. I re ally liked you,‖ she sobbed.But in the final episode, the woman he eventually chose decided she didn’t want to marry him after all. ―I think you’ve chosen me because you have to choose someone,‖ she said. Maybe this was because she already knew he had fallen in love---with the show’s host!After leaving the show, Gerrard-Wright and Johnson were seen dining together and attending parties around London more and more often. Finally, on May 1, 2003, Gerrard-Wright proposed to Johnson on the steps of St. Paul’s Cathedral. And she accepted his proposal right away, although it was a conditional acceptance. Johnson has two children from previous relationships—aneight-year-old son, Cameron, and a two-year-old daughter, Bo. She had to make sure that they agreed to the marriage. Luckily, they did. Gerrard-Wright said, ―In the end the show did work for me. I grabbed an opportunity to get a girlfriend and I did. Ulrika’s gorgeous.‖Questions 66-68Complete the following sentences with information given in the passage in a maximum of 2 words for each blank.66.

Lance started to date with the show’s host.C. One of the women on the show couldn’t help crying.D. Ulrika asked Lance to marry her.Section D (10 marks)Questions 71-75 are based on the following passage.Alaska is disappearing slowly but surely. Since the 1950s, it is estimated that as much as 15 percent of Alaska’s area has disappeared. But how can a whole state be disappearing?One reason for Alaska’s gradual disappearance is the melting its glaciers. According to one geologist at the US Geological Survey, about 98 percent of Alaska’s glaciers are either unmoving or diminishing. This diminishing seems mainly due to the increase in global temperatures. Since the 1960s, the average year-round temperature has increased by 5℉. Furthermore, the average winter temperature has increased by 8℉. Presently, an estimated 24 cubic miles of ice is disappearing from Alaskan glaciers every year. It may be even more in the near future, as some scientists predict that the average world temperature could go up 2.5 to 10℉by the year 2010.Another problem contributing to Alaska’s gradual disappearance is its permafrost. (74) Much of the land in Alaska was permanently frozen, or frozen for most of the year, thus maintaining its integrity. Now, the thawing permafrost is causing a number of problems on land. Roads and utility poles are collapsing. Also, the hard permafrost which originally prevented beaches from eroding during violent storms is now melting. Affected villages are forced to relocate. For villages on small low islands, one terrible storm could wipe out the entire community.The melting permafrost and increasing temperature are also having a negative impact on the forests of Alaska. As the permafrost under the forests melts, insects that normally don’t turn upuntil the warmer seasons are appearing sooner. The spruce-bark beetle, for example, is increasing in numbers as a result of global warming. It usually takes about two years for these beetles to grow and reproduce in a very cold weather. However, due to the increase in temperatures, spruce-bark beetles are damaging as many trees in one year as they previously damaged in two. At this rate, Alaska’s forest won’t survive the turn of the century.Some scientists believe that human activity is linked to a global increase in weather temperature. Whether the rising temperature are caused by human activity or natural changes, the fact remains that Alaska is warming. Some others argue that global warming may be a normal trend on the Earth’s temperature chart. (75) One theory argues that we are near the end of aso-called ―Little Ice Age‖, and the return of the glaciers is natural result of this cycle. Whether natural or produced by humans, there is little hope for the immediate future of glaciers as we know them. Horribly, this could be a preview of what will happen to the rest of the world in the next century.Questions 71-73Answer the following questions briefly according to the passage.71.
