 这是我自己写的一个程序，请问我如何把这个程序分为三个自己定义的函数，然后再主函数中直接调用。分为1：读入文件，将数据存储在数组；2：冒泡排序。3：输出结果。请在我程序的基础上修改一下，谢谢了。

嗯嗯，有必要帮助一下

#include <iostream>
#include <fstream>
#include <cstring>

using namespace std;

ifstream & fileopen(ifstream &fin,int &themax,string *name,int sumtime[],int time[][50])
{

      fin.open("d:\\fish.txt");

        fin >> themax;
        for(int i=0; i<themax; i++) {
        fin >> name[i];
        for(int j=0; j<7; j++) {
            fin >> time[i][j];
            sumtime[i] += time[i][j];
        }
    }
    fin.close();
}
void getorder(int sumtime[] ,int themax,string *name,int  time[][50])
{


    for(int i=0; i< themax; i++) {
        cout << name[i] << " ";
        for(int j=0; j<7; j++) {
            cout << time[i][j] << " ";
        }
        cout << sumtime[i] << endl;
    }

    for (int i = 0; i<themax-1; i++) {
        int k = i;
        int minnum;
        for (int j=i+1; j<themax; j++) {
            minnum = sumtime[i];
            if (sumtime[j] < sumtime[k]) {
                k = j;
            }
        }
        if(i != k) {
            swap(name[i], name[k]);
            swap(sumtime[i], sumtime[k]);
            for (int n=0; n<7; n++) {
                swap(time[i][n], time[k][n]);
            }
        }
    }

}
void out(int sumtime[] ,int themax,string *name,int  time[][50])
{
     cout << "******************" << endl;
    for(int i=0; i< themax; i++) {
        cout << name[i] << " ";
        for(int j=0; j<7; j++) {
            cout << time[i][j] << " ";
        }
        cout << sumtime[i] << endl;
    }
}
int main() {
    ifstream fin;
    int sumtime[50] = {0};
    int themax;
    string name[50];
    int time[50][50];

    fileopen( fin, themax, name, sumtime, time);
    getorder(sumtime ,themax,name,time);
    out(sumtime ,themax,name,time);



    return 0;
}

呵呵忘了返回了哈

ifstream & fileopen(ifstream &fin,int &themax,string *name,int sumtime[],int time[][50])
{

      fin.open("d:\\fish.txt");

        fin >> themax;
        for(int i=0; i<themax; i++) {
        fin >> name[i];
        for(int j=0; j<7; j++) {
            fin >> time[i][j];
            sumtime[i] += time[i][j];
        }
    }
    fin.close();
    return fin;
}

以上在CB中可以通过
