建筑解决方案有时仅打印阵列吗？

Question

我正在尝试以随机生成的2d char数组的形式制作2d地图。事实是，它有时仅打印，我不知道为什么。我猜在某些情况下它无法按计划进行并且根本无法打印？如果另一双眼睛可以指出任何事情，我将不胜感激。我这堂课有4张不同的地图，但是没有一张能一致打印。

如果需要，这是.h文件

#ifndef MAP_H
#define MAP_H

#include <iostream>
#pragma once

    Map(); // generate map
    ~Map();

    char getTerrainAt(int, int);

    float getPositionAt(int, int);
    void setVisualAt(int, int, char);
    char getVisualAt(int, int);
    void setPlayerMapAt(int, int, char);
