c++ - C++调试错误

当我运行下面编写的程序时，出现运行时检查失败＃2-变量'NewImage'周围的堆栈已损坏。我怎样才能解决这个问题？我知道这与超出变量的内存限制有关，但我不确定要更改什么。谢谢！

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

const int ROWS = 16;
const int COLS = 16;

enum flipType {HORIZONTAL, VERTICAL};

void getImage(char img[][COLS]);
void print(const char img[][COLS], string msg);
void flip(const char img[][COLS], char NewImage[][COLS], flipType);
void negative(const char img[][COLS], char NewImage[][COLS]);
void rotate(const char img[][COLS], char NewImage[][COLS], rotateType);

int main()

        cout << endl;
    }

            }
        }
    }
}

最佳答案

取代这个

NewImage[i][-j-1]= img[i][j];

有了这个

NewImage[i][COLS-j-1]= img[i][j];

不知道为什么自从正确翻转垂直后就无法发现自己​​，并且对问题所在有很好的了解。我想需要学习仔细查看自己的代码。
