Answer 1

#include <stdio.h>

int main()
{
    int n, count = 0, a = 0, b = 0, c = 0, xcnt = 0;
    while (1)
    {
        scanf("%d", &n);
        if (n == -1)
            break;
        if (n == 1)
            a++;
        if (n == 2)
            b++;
        if (n == 3)
            c++;
        if (n >= 1 && n <= 3)
            xcnt++; // 有效票
        count++;    //所有票
    }
    printf("A=%d\n", a);
    printf("B=%d\n", b);
    printf("C=%d\n", c);
    printf("Tot=%d\n", xcnt);
    if (a * 1.0 / count > 0.5)
        printf("A-yes");
    else if (b * 1.0 / count > 0.5)
        printf("B-yes");
    else if (c * 1.0 / count > 0.5)
        printf("C-yes");
    else
        printf("all-NO"); //题目结果是按所有票统计的，因此为No

    return 0;
}
