c语言用while和dowhile分别编写一个求和程序 – java – 前端

while求和代码

#include <stdio.h> int main() {int i = 0, sum = 0, n;scanf (“%d”, &n);while (i <= n){sum += i;i++;}printf (“%d “, sum); }

do—while求和代码

#include <stdio.h> int main() {int i = 0, sum = 0, n;scanf (“%d”, &n);do{sum += i;i++;}while (i <= n);printf (“%d “, sum); }
