求多个整数和，输入非数字才开始求和，帮我看看
#include<stdio.h>
int main()
{
    int sum=0,value=0;
    while(scanf("%d",&value))
    {
        sum+=value;
    }
    printf("%d",sum);
    return 0;
}

运行无误

    while(scanf("%d",&value))
    {
        sum+=value;
    }
你是如何结束这个循环的？

“输入非数字才开始求和” --- 这是你的要求呢，还是你想解决掉的bug？

Return Value

Both scanf and wscanf return the number of fields successfully converted and assigned; the return value does not include fields that were read but not assigned. A return value of 0 indicates that no fields were assigned. The return value is EOF for an error or if the end-of-file character or the end-of-string character is encountered in the first attempt to read a character.
