这是一个求π近似值以及循环次数的程序，请教各路高手有什么问题，我运行不出来。
#include<stdio.h>
#include<math.h>
int main()
{
    int n = 1, sign = 1, m = 0;
    double pi = 0.0, t=1.0;
    while (fabs(t) >= 1e-6)
    {
        pi = pi + t;
        n = n + 2;
        sign = -sign;
        t = sign / n;
        m++;
    }
    pi = pi * 4;
    printf("%f,%d", pi , m);
    return 0;
}
答案是这个，你们参考下：
#include<stdio.h>
#include<math.h>
int main()
{
    int sign = 1, count = 0;
    double pi = 0.0, n = 1.0, term = 1.0;
    while (fabs(term) >= 1e-6)
    {
        pi = pi + term;
        n = n + 2;
        sign = -sign;
        term = sign / n;
        count++;
    }
    pi = pi * 4;
    printf("%10.6f,%d", pi, count);
    return 0;
}
