1. 安装拓展

Chinese是中文，需要重启才可以运行，C/C++拓展只是进行语法代码提示，不需要进行任何配置修改，默认即可。

2. 创建文件

C++是工作文件夹，.vscode是配置文件夹，里面建一个tasks.json文件，然后把下面内容复制进去

{
	"version": "2.0.0",
	"tasks": [
		{
            "label": "build",
            "type": "shell",
            "command": "g++", // 如果没有配置环境变量可以直接改成g++.exe的文件路径
            "args": [
                "${file}",
                "-o",
                "${fileDirname}\\${fileBasenameNoExtension}.exe",
                "-g",
                "-Wall",
                "-fexec-charset=GBK",
                "-std=c++11"
            ],
            "group": "build",
            "presentation": {
                "echo": true,
                "reveal": "always",
                "focus": false,
                "panel": "shared"
            },
            "problemMatcher": "$gcc"
        },
		{
            "label": "run",
            "type": "shell",
            "dependsOn": "build",
            "command": "${fileDirname}\\${fileBasenameNoExtension}.exe",
            "group": {
                "kind": "test",
                "isDefault": true
            },
            "presentation": {
                "echo": true,
                "reveal": "always",
                "focus": true,
                "panel": "shared",
                "showReuseMessage": true,
                "clear": true
            }
        }
	]
}

3. 绑定快捷键

这样就配置好了，通过快捷键运行代码，会在终端进行输入输出交互。注意，这样配置是没有debug能力的，不过竞赛选手普遍都是肉眼debug，不需要这个功能。

4. 刷题模板

#pragma GCC optimize(3, "Ofast", "inline")
#include<bits/stdc++.h>
#define int long long
#define x first
#define y second
#define pc putchar
#define debug(x) cerr << #x" = " << x << '\n';
using namespace std;
inline int rd() { int X = 0, w = 0; char ch = 0; while (!isdigit(ch)) { w |= ch == '-'; ch = getchar(); } while (isdigit(ch)) X = (X << 3) + (X << 1) + (ch ^ 48), ch = getchar(); return w ? -X : X;}
inline void wr(int x) { if (x < 0) pc('-'), x = -x; if (x > 9) wr(x / 10); pc(x % 10 + '0');}

void solve()
{
    
}

signed main()
{
    int _ = 1;
    // cin >> _;
    while (_ --) solve();
    return 0;
}
