c++ - 错误 'map' 未在此范围内声明

Question

试图完成我的个人项目，但我陷入了这个问题。我正在制作一款 2d 游戏，并认为我已经设置得很好，但我得到了一个错误，这基本上表明我的变量之一没有在多个范围中声明。这是我的代码，试图制作一个简单的 2d 游戏，试图在 Linux 中编译和运行。

错误具体指出:

project.cpp:52:7: error: 'map' was not declared in this scope

 if(map[y2][x] == '^') {


#include <iostream>
#include <cstdlib>

using namespace std;

cout << "Help the Brave adventurer, &, find his way through the maze, to reach the Treasure, $$!"

char map[17][21] = {                
    "Use W,A,S,D to move"
    "Press X to end game"   
    "####################",
    "# & ##      ##  # ^#",
    "#   ##^        ^# ^#",

Answer 1

1. 尝试将变量重命名为“map ”以外的名称，因为它也代表 std::map .

2. 第一行“if(map[y2][x] == '^') {”是拼写错误吗？

3. 我认为你必须移动它 cout << "Help the Brave adventurer, &, find his way through the maze, to reach the Treasure, $$!"进入main()
