有无好朋友可以帮我看看这个问题

看可不可以写出来

#include<stdio.h>
int main()
{
    int n,res=0;
    scanf("%d",&n);
    int num;
    while(n != 0)
    {
        if(n >= 50)
        {
            num = n/50;
            res += num*7;
            n = n - num*50;
        }
        else if(n>=30)
        {
            num = n/30;
            res += num*4;
            n = n - num*30;
        }
        else
        {
            num = n/10;
            res += num*1;
            n = n - num*10;
        }
    }
    printf("%d",res);
    return 0;
}

觉得有用的话采纳一下哈

#include<stdio.h>

int main(void){
int N,sum;
scanf("%d",&N);
sum=(N/50)2+((N-50(N/50))/30)*1+N/10;
printf("%d",sum);
}
