程序代码：

#include<stdio.h>
int main()
{
    int  sum = 0, s, max, i = 0;
    while (1) {
        scanf("%d", &s);
        if (s < 0)  break;
        if (i == 0) max = s;
        else {
            if (max < s) max = s;
        }
        sum += s;
        i++;
    }
    printf("avg = %f,max = %d", (float)sum / i, max);
    return 0;
}
