实验十九：编写一个万年历系统1.设计目的：从实验的角度来看，这次课程设计一方面可以让自己巩固并加深对C语言程序设计知识的理解，掌握和提高C语言编程和程序的基本调试的基本技能，进一步理解和运用结构化程序的思想和方法；另一方面，可以让自己在面对一个全新的问题时，学会如何思考，如何寻找问题的关键，从而提升自己的能力。

2.总体设计：1.、当前页以系统当前日期的月份为准，显示当前月的每一天（显示出日及对应的星期几）；2、当系统日期变到下一个月时，系统自动翻页到下一月。

3.调试与测试：4.源程序清单和执行结果：#include <stdio.h>#include <conio.h>#include <stdlib.h>#include <time.h>int leap(int year ){if ((year %4 == 0) && (year % 100 != 0)|| (year % 400 == 0)){return 1;}return 0;}void show(int year,int month,int date,int sec,int mini,int hour) {const char month_str[][4]={"","Jan","Feb","Mar","Apl", "May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"};const int month_day[]={0,31,28,31,30,31,30,31,31,30,31,30,31}; int i,j,wdays,mdays,days;for(i=1,days=0;i<year;i++){if(leap(i)){days += 366;}else{days += 365;}}for(i=1;i<month;i++){if(i==2 && leap(year)){days+=29;}else{days+=month_day[i];}}printf(" %s.%d.%d %d:%d:%d \n",month_str[month],date,year,hour,mini,sec);printf(" 一二三四五六日\n");wdays = days % 7;for( j = 0; j < wdays; j++){printf(" ");}if(month == 2 && leap(year)){mdays=29;}else{mdays= month_day[month];}for(i=1;i<=mdays;i++){if( i > 1 && days % 7 == 0 ){Printf(“\n”);printf("\n");}printf("%4d",i);days=days+1;}printf("\n---------------------------\n\n\n");}void main(){time_t rawtime;struct tm *info;int year,month,date,sec,mini,hour; char ch;time ( &rawtime );info = localtime ( &rawtime );year =info->tm_year + 1900; month =info->tm_mon + 1;date =info->tm_mday;hour =info->tm_hour;mini =info->tm_min;sec =info->tm_sec;while(1){show(year,month,date,sec,mini,hour); printf("↑......上一年\n\n");printf("↓......下一年\n\n");printf("←....前一个月\n\n");printf("→....后一个月\n\n");printf("Esc.......退出\n\n");ch=getch();switch(ch){case 27://Ecsexit(0);case -32://Navigatorch=getch();if(ch==77){//Rightyear+=(month==12)?1:0;month=month%12+1;}else if(ch==75){//Leftyear-=(month==1)?1:0;month=(month-2+12)%12+1;}else if(ch==72) {//Upyear--;}else if(ch==80) {//Downyear++;}system("cls"); }}}。
