c语言代码解决问题

解题思路:

注意事项:

参考代码:

#include<stdio.h>

int main()

{

    int n,a[100],i;

    scanf("%d", &n);

    for(i=0;i<n;i++)

        scanf("%d",&a[i]);

    int sum_1 = 0, sum_5 = 0, sum_10 = 0;

    for (i = 0; i < n; i++)

    {

        if (a[i] == 1)

            sum_1++;

        else if (a[i] == 5)

            sum_5++;

        else if (a[i] == 10)

            sum_10++;

    }

    printf("%d\n%d\n%d\n", sum_1, sum_5, sum_10);

    return 0;

}
