这是main.cpp文件，一切似乎工作正常，直到我点击＆＃34; Arr = ship1.retrieve（）＆＃34;功能调用。
#include<iostream>
#include<string>
#include"ship.h"
using namespace std;
int main(){
int newarray[5][5] = {
0, 0, 1, 0, 0,
0, 1, 1, 1, 0,
1, 1, 1, 1, 1,
0, 1, 1, 1, 0,
0, 0, 1, 0, 0
};
int arr[80][24];
int *Arr;
ship ship1(newarray, 1);
ship1.spawn(40, 12);
Arr = ship1.retrieve();
system("pause");
delete Arr;
}
这是上面调用的检索成员函数：
int *retrieve(){
int *p = new int[1920];
for (int i = 0,x = 0; i <= 80; i++, x++)
{
for (int o = 0; o <= 24; o++, x++)
{
p[x] = bArray[i][o];
}
}
return p;
}
这些是我得到的错误/例外：

The program '[15204] text-based game engine.exe' has exited with code -1073741510 (0xc000013a).
还值得一提的是在函数调用之后出现了一些错误，这似乎是一个内存分配问题（我对c ++来说相对较新）。

如果有人能解释为什么会发生这种情况，我将永远感激不尽。感谢任何回复的建议！
答案 0 :(得分：0)
我看到的一件事是你的班级成员int bArray[80][24]正在通过循环进行迭代：
for (int i = 0,x = 0; i <= 80; i++, x++)
{
for (int o = 0; o <= 24; o++, x++)
{
p[x] = bArray[i][o];
}
}
这个问题是你因为＆lt; =操作数而分别遍历循环81和25次。这将在双数组之外进行索引。
编辑：这也意味着考虑到以下行，x被迭代次数太多次了：
int *p = new int[1920];
