所以我有一个包含团队和分数的文件，我需要将团队读入一个二维字符数组，然后将他们的分数读入一个整数数组。

这是我当前的函数代码，如何在团队名称完成后停止阅读，然后将分数存储在单独的数组中？

void getData (char array [][COLS], int rows, int scores [])
{
    ifstream inFile;     //Input file stream object

    //Open the file
    inFile.open ("scores.txt");

     if (!inFile)
    {
        cout << "Error opening data file!\n";
        exit(102);
    }

    for (int r = 0; r < rows; r++)
    {
        {
            //reads through columns
            for (int c = 0; c < COLS; c++)
            {
                inFile >> array[r][c];
            }
        }
    }

    for (int count = 0; count < ROWS; count++)
    {
        for(int i = 0; i < COLS; i++)
        {
            cout << array[count][i];
        }
    }

    inFile.close();
}

我的输入文件如下：

Jaquars 23
Colts 23
49ers 13
Lions 13
Titans 7
Redskins 38
Cardinals 14
Buccaneers 36
Seahawks 30
Lions 24
Bears 28
Packers 23
Bears 14
Rams 22
Texans 6
Packers 34
4

这就是我的代码

void getData (char array [][COLS], int rows, int scores [])
{
     ifstream inFile;     //Input file stream object

    //Open the file
    inFile.open ("scores.txt");

     if (!inFile)
    {
        cout << "Error opening data file!\n";
        exit(102);
    }

for (int r = 0; r < rows; r++)
{
    int c = 0;
    char ch;
    // keep reading until we hit a space
    ch = inFile.get();
    while (ch != ' ')
    {
        array[r][c] = ch;
        c++;
        ch = inFile.get();
    }
    // now read the score
    inFile >> scores[r];
    // now read until we hit the trailing newline
    ch = inFile.get();
    while (ch != '\n' && ch != EOF)
    {
        ch = inFile.get();

    }
}

        for (int count = 0; count < rows; count++)
        {
            for(int i = 0; i < COLS; i++)
            {
                cout << array[count][i];
                for (int count2 = 0; count2 < rows; count2++)
                    cout << scores[count2];
            }
        }

    inFile.close();

    return;
}

这应该让你知道如何去做。我没有编译它。但可以很好地说明这一点。我强烈建议您使用基于地图的解决方案。或者使用向量。

#include <string>
#include <iostream>
#include <fstream>
#include<cstring>
#include<cstdlib>
using namespace std;

int main() 
{   
    ifstream in("DataFile.txt");
    string line;
    char * pch;

    while(getline(in, line))
    {
        pch = strtok (line.c_str()," ");
        while (pch != NULL)
        {
            //Put some logic here so that in first loop iteration
            //first segment(name) gets stored in your char arrays.
            //In second iteration, which will return the score, you store that
            //in the int array. Do not forget to use atoi() to convert to int before storing.
            pch = strtok (NULL," ");
        }
    }

    //There are more elegant ways to split a string in C++
    //http://stackoverflow.com/questions/236129/how-to-split-a-string-in-c
    return 1;
}

也许像这样

for (int r = 0; r < rows; r++)
{
    int c = 0;
    // keep reading until we hit a space
    char ch = inFile.get();
    while (ch != ' ')
    {
        array[r][c] = ch;
        c++;
        ch = inFile.get();
    }
    // now read the score
    inFile >> scores[r];
    // now read until we hit the trailing newline
    ch = infile.get();
    while (ch != '\n')
    {
        ch = inFile.get();
    }
}
