当我尝试运行我的代码时，它编译没有问题。但是，当我尝试运行它时，我得到line x: segmentation fault, x 是错误所在的行，但是每次我尝试再次运行该程序时它都会更改 +1，这看起来很奇怪。下面是相关代码：

#include <iostream>
#include <fstream>
#include <string>
#include "image.h" // Has the prototypes for the functions

using namespace std;   

int** load(string imageFile, int &length, int &height) {
    ifstream file(imageFile);
    if(file.is_open()) {
        file >> length; 
        int** array = new int*[length];
        file >> height;
        for(int i = 0; i < length; i++) {
            array[i] = new int[height]; 
            for(int j = 0; j < height; j++) {
                file >> array[i][j];
                if(array[i][j] > 255 || array[i][j] < 0) {
                    cout << "Image is corrupted." << endl;
                    file.close();
                    return 0;
                }
            }
        }
        file.close();
        return array;
    }
    else {
        cout << "Unable to open file." << endl;
        return 0;
    }
}

void show(int **image, int length, int height) {
    cout << "The height of the matrix is: " << height << endl;
    cout << "The length of the matrix is: " << length << endl;
    cout << "The matrix is: " << endl;
    for(int i = 0; i < length; i++) {
        for(int j = 0; j < height; j++) {
            cout << " " << image[i][j]; 
        }
        cout << endl;
    }
}

int main() {
    int height = 0;
    int length = 0;
    int **image = load("../resource/imagecorrupted.txt", length, height);
    image = load("../resource/image.txt", length, height);
    show(image, length, height);
}

这是输出： Image is corrupted. Image is corrupted. //Not sure why this shows twice to be honest The height of the matrix is: 8 // but that seems like the least of my worries The length of the matrix is: 10 The matrix is: -bash: line xx: xxxxx Segmentation fault

不知道是什么原因造成的，任何帮助表示赞赏！

我完全忘记了显示输入的含义。我道歉。他们来了： 10 8 0 255 255 255 0 0 255 255 255 0 255 0 255 255 0 0 255 255 0 255 255 255 0 255 255 255 255 0 255 255 255 255 255 0 255 255 0 255 255 255 255 255 255 355 0 0 255 255 255 255 255 255 255 255 0 0 255 255 255 255 255 255 255 0 255 255 0 255 255 255 0 0 0 255 255 255 255 0 0 0

这就是包含在image.txt. imagecorrupted.txt是相同的，只有一个值从 255 切换到 355（有意失败）。的10和8是矩阵的长度/高度。

编辑2：

试图delete在每次load调用之间添加一个函数，但无济于事，尽管我确定这里有一些我没有得到的东西。这是使用的代码：

void free(int **image, int &length, int &height) {
    if(image) {
        for(int i = 0; i < length; i++) {
            if(image[i]) {
                delete[] image[i];
            }
        }
        delete[] image;
    }
}

我所做的主要是：

 int **image = load("../resource/imagecorrupted.txt", length, height);
 free(image, length, height);
 image = load("../resource/image.txt", length, height);
