尝试着创造一款原始的主机蛇游戏.0警告/论述.为什么我的程序崩溃了?(c++)

感谢您的阅读。我是一个开始的程序员，我试图用c++做一个简单的蛇游戏。它还没有完成，但我想我有一个很好的开始。然而，当我试图运行该程序时，它立即崩溃。(编译器说没有警告和错误。我正在使用Code::Blocks IDE。有人知道为什么我的程序不工作吗?我认为这可能与"矢量坐标历史"有关，但我不能确定。至少这是我在程序中添加的最后一件事。

这是我的代码:

    #include <iostream>
    #include <cstdlib>
    #include <string>
    #include <cstdio>
    #include <windows.h>
    #include <conio.h>

    #define MAXX 156 //Number of columns that fits on my screen
    #define MAXY 62 //Number of rows that fits on my screen
    using namespace std;
    // This function clears the console window
    void clearConsole()
    {
        system("cls"); //empties console window
    };
    // This function returns the x position of the cursor
    int getcursorX()
    {
        CONSOLE_SCREEN_BUFFER_INFO csbi;
        if(GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi)) {
            return csbi.dwCursorPosition.X;
        }
    };
    // This function returns the y position of the cursor
    int getcursorY()
    {
        CONSOLE_SCREEN_BUFFER_INFO csbi;
        if(GetConsoleScreenBufferInfo(GetStdHandle(STD_OUTPUT_HANDLE), &csbi)) {
            return csbi.dwCursorPosition.Y;
        }
    };
    // This function sets the x position of the cursor
    void setcursorX(int x)
    {
        COORD coord = {x, getcursorY()};

    }
    // This function sets the y position of the cursor
    void setcursorY(int y)
    {
