while和do while函数的运用

while函数

#include<stdio.h>
int main() {
int i=0;
int sum = 0;
scanf_s("%d", &i);
while (i <= 10) //满足则循环，不满足则输出
{
printf("%d ", i);
sum += 1;//sum=sum+1
i = i + 1;
}
printf("sum=%d ", sum);
return 0;
}

do while函数

#include<stdio.h>
int main(){
int n = 0;
scanf_s("%d", &n);
do {
printf("%d ", n);
n = n - 1;
} while (n >= 1);
return 0;
}
