急 寻找c语言题目解答

供参考：

#include<stdio.h>
int main()
{
    int    n, cnt_e = 0, cnt_o = 0;
    double sum_e = 0.0, sum_o = 0.0;
    while (scanf("%d", &n) == 1 && n != 0)
    {
        if (n % 2 == 0)
        {
            cnt_e++;
            sum_e += n;
        }
        else {
            cnt_o++;
            sum_o += n;
        }
    }
    printf("Number of even:%d;Average of even:%.2f\n", cnt_e, sum_e / cnt_e);
    printf("Number of odd:%d;Average of odd:%.2f\n", cnt_o, sum_o / cnt_o);
    return 0;
}
