可以运行 没错误 没警告 但是不会出结果。

两个地方有问题

void Find(int number[], double *pMax, double *pMin, double *pAver1, double *pAver2)
{
    int j, m, sum1, sum2, count1, count2, count3;
    m = 0;
    sum1 = 0;
    sum2 = 0;
    count1 = 0;
    count2 = 0;
    count3 = 0;

    *pMax = number[0];
    *pMin = number[0];
    *pAver1 = 0;
    *pAver2 = 0;

    for (j = 0; j<300; j++)
    {
        count2 = 0;
        if (number[j]>*pMax)
        {
            *pMax = number[j];
        }

        if (number[j]<*pMin)
        {
            *pMin = number[j];
        }

        if (number[j] % 2 != 0)
        {
            sum1 += number[j];
            count1++;
        }


        for (m = 2; m<number[j]; m++)
        {
            if (number[j] % m == 0)
            {
                count2++;
            }
        }
        if (count2 == 0)
        {
            sum2 += number[j];
            count3++;
        }

    }
    *pAver1 = sum1 / count1;
    *pAver2 = sum2 / count3;
}

可以啦 十分感谢哈。
