题解 | 统计数据正负个数

#include <stdio.h>

int main() {
    int a, po = 0, ne = 0, i = 10;
    while (scanf("%d", &a) != EOF) { 
        if(a > 0)
            po++;
        else
            ne++;
            i--;
            if(i == 0)
                break;
    }
    printf("positive:%d\nnegative:%d\n",po,ne);
    return 0;
}

记得给个变量控制循环
