c++ - 文件读取程序有...黑屏问题

Question

好的，所以我在这方面遇到了一些麻烦。这是家庭作业，特别是我最后的 C++ 编程，但我有我认为是逻辑缺陷的东西。此时它应该做的就是从指定文件中读取信息，将其存储在一对平行的二维数组中(一个用于字符串数据，另一个用于数字数据)，然后将其打印到屏幕上。尚未放入任何其他内容，直到项目的后半部分才需要。

当我运行代码时，它会加载控制台窗口，然后空白。如果有人能指导我解决问题的大致范围，我将不胜感激。

#include <iostream>
#include <string>
#include <fstream>
#include <iomanip>

using namespace std;

void readFile(int numericData[80] [4], string textData[80] [7]);
void printData(int numericData[80] [4], string textData[80] [7]);

int main()
{
    string trash;
    string textData [80] [7];
    /* columns: 0 = name 1 = Weakness 2 = drops
    3 = stealables 4 = poach item
    5 = appearnce type 6 = location */

    int numericData [80] [4];
    // columns: 0 = HP 1 = XP 2 = LP 3 = diff rank
    // used 2 multi-dimensional parallel arrays to avoid 10 parallel arrays

    readFile(numericData, textData);
    printData(numericData, textData);

    return 0;
}

void readFile(int numericData[80] [4], string textData[80] [7])
{
    ifstream inputFile;
    inputFile.open("filename");

    string trash;
    string rankConverter;
    for (int i = 0; i < 169; i++)
    {
        getline(inputFile, trash);
    }
    //throws out first 173 trash lines, until first usale line.


    for (int rareReader = 0; rareReader < 80; rareReader++)
    {
        // edited for brevity. this section reads each individual component
        // of the file and inserts them into the appropriate array section.

        do
        {
            getline(inputFile, trash);
        }
        while (trash != "end-entry marker");
        // throws away the rest of each entry as trash
    }
    //felt it relevant to mention that the following close command is before all
    //lines of the file have been read and thrown out. not sure if relevant.
    inputFile.close();
}



void printData(int numericData[80] [4], string textData[80] [7])

    cout << setw(20) << "Steals";
    cout << setw(20) << "Location";



    for (int printCount = 0; printCount < 80; printCount++)
    {
        cout << setw(10) << textData[printCount][0];
        cout << setw(10) << numericData[printCount][0];

程序很可能卡在某处。尝试在程序开始时打印到屏幕。如果可行，则继续添加“cout”调用以打印更多调试消息，直到找到程序挂起的位置。这是一种您将反复使用的调试方法。有时称为“穴居人”调试，因为更高级的替代方法是附加调试器并单步执行代码。
