【贪污腐败】中国科协调查显示国内科研经费仅40%用于项目

计算机二级C语言上机(南开大学）100题程序填空题1 补充fun函数，fun函数的功能是求10的阶乘。

n>1 n-1 n==12 在函数fun的横线上填写若干表达式，使从键盘上输入一个整数n，输出数列是一种整数数列，其中每数等于前面两数之和n==o n==1 fun(n-1)+fun(n-2)3 补充函数fun(char*s),该函数的功能是把字符串中的内容逆置s+i<s+n-1-i*(s+i)=(s+n-1-i) *(s+n-1-i)=t4 补充函数fun，他的功能是计算并输出n（包括n)以内能被3或7整除的所有自然数的倒数之和i<=ni%3==0||i%7==0 1.0/i5 功能是求1/2的圆面积，函数通过形参得到圆的半径，函数返回1/2的圆面积r r*r &x6 功能是计算并输出下列级数的前N项合Sn,直到Sn大于q为止，q 的值通过形参传入<= n++return s7 函数fun的功能是统计长整数n的各个位上出现数字1.2.3的次数，并通过外部（全局）变量c1.c2.c3返回主函数n%10 break break8 补充main函数，功能是从键盘输入一组整数，使用条件表达式找出最大的整数，当输入的整数为0时结束&num[i]max<num[i]? num[i]!=09 给定程序的功能是分别统计字符串中大写字母和小写字母的个数(*a)++ (*b)++ upper,lower10 补充main函数，功能是从键盘输入3个整数，然后找出最大的数并输出。

max=a max=b max=c11 函数fun的功能是把形参s所指字符串中下标为奇数的字符右移到下一个奇数位置，最右边被移出字符串的字符绕回放到第一个奇数位置，下标为偶数的字符不动1 s[k] c12 补充fun函数，功能是字符串tt中的大写字母都改为对应的小写字母，其他的字符不变。

tt[i]<='Z'tt[i]+=32 tt13 补充fun函数，功能是判断一个数是否为素数。
