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 m,consume=0;

    char demand;

    scanf("%d %c",&m,&demand);

    if (m <= 1000)

    {

        consume += 8;

    }

    else

    {

        consume += 8;

        int mod;

        mod = (m-1000) / 500;

        consume += mod * 4;

        if ((m - 500 * mod-1000) % 500 != 0)

            consume += 4;

    }

    if (demand == 'y')

        consume += 5;

    printf("%d", consume);

    return 0;

}
