为啥我在本地输入之后,按下Enter并不会运行啊?用的vs
#include<stdio.h>
int main()
{
int num;
double score, total;
num = 0;
total = 0;
printf("请输入学生的成绩:\n");
scanf_s("%lf", &score);
while (score >= 0)
{
total = total + score;
num++;
scanf_s("%lf", &score);
}
if (num != 0)
printf("平均成绩为: %.2f\n", total / num);
printf("总成绩为: %.2f\n", total);
if (num == 0)
printf("平均成绩:0\n");
return 0;
}
