#include <string.h>

using namespace std;



int main()
{

    int n;
    int val;  //用于缴纳
    char name[10];
    //一共有5人
    int banf[5];
    for(int i=0;i<5;++i)

        banf[i]=10; //初始每人缴纳10元班费
    }

            }
            if(!isFind)
            {

            }
        }
        if(n==1)
        {
            printf("请输入要缴纳的姓名:\n");
            scanf("%s",&name);
            bool isFind=false;
            for(int i=0;i<5;++i)
            {

                {
                    isFind=true;
                    printf("请输入需要缴纳的金额\n");
                    scanf("%d",&val);
                    banf[i]+=val;
                    printf("%s已缴纳班费%d元\n",jiaofeimingdan[i],banf[i]);
                    break;
                }
            }
            if(!isFind)
            {
               printf("未找到该学生,请重新选择!\n");
            }
        }
        if(n==2)
        {
            break;
        }

    }

    return 0;
}
