统计每一行质数的个数，为啥我这里出来的个数都是0？

Question

Answer 1

代码修改如下，如有帮助，请帮忙采纳一下，谢谢：

#include <stdio.h>
int main()
{
    int n,m,i,count,x,isPrime;
    scanf("%d",&n);
    count = 0;
    for (m = 1;m<=n;m++)
    {
        count = 0;
        scanf("%d",&x);
        while(x != -1)
        {
            for(i=2,isPrime = 1;i<x;i++)
            {
                if(x%i == 0)
                {
                    isPrime = 0;
                    break;
                }
            }
            if(isPrime == 1)
                count++;
            scanf("%d",&x);
        }
        printf("%d\n",count);
    }
    return 0;
}
