vscode创建c、c++环境，tasks.json和launch.json文件配置

vscode创建c、c++环境

注：主要是记录一下tasks.json和launch.json（自测可用），并不详细讲解安装过程。
Talk is cheap，show me the code!!

1. 安装vscode
2. 安装vscode插件（c/c++，vscode插件一搜就有）
3. 安装mingw并配置环境变量
4. 新建c/c++文件
5. 编辑或创建tasks.json和launch.json

tasts.json

{
    //See https://go.microsoft.com/fwlink/?LinkId=733558 
    //for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",
            "label": "g++", //这里注意一下，见下文
            "command": "D:\softwares\coding\mingw-w64\x86_64-8.1.0-release-posix-seh-rt_v6-rev0\mingw64\bin\g++.exe",
            "args": [
                "-g",
                "${file}",
                "-o",
                "${fileDirname}\${fileBasenameNoExtension}.exe"
            ],
            "options": {
                "cwd": "D:\softwares\coding\mingw-w64\x86_64-8.1.0-release-posix-seh-rt_v6-rev0\mingw64\bin"
            },
            "problemMatcher": [
                "$gcc"
            ]
        }
    ]
}

//launch.json
{   
   "version": "0.2.0",  
    "configurations": [  
        {  
            "name": "(gdb) Launch", // 配置名称，将会在启动配置的下拉菜单中显示  
            "type": "cppdbg",       // 配置类型，这里只能为cppdbg  
            "request": "launch",    // 请求配置类型，可以为launch（启动）或attach（附加）  
            "program": "${workspaceFolder}/${fileBasenameNoExtension}.exe",// 将要进行调试的程序的路径  
            "args": [],             // 程序调试时传递给程序的命令行参数，一般设为空即可  
            "stopAtEntry": false,   // 设为true时程序将暂停在程序入口处，一般设置为false  
            "cwd": "${workspaceFolder}", // 调试程序时的工作目录，一般为${workspaceFolder}即代码所在目录  
            "environment": [],  
            "externalConsole": false, // 调试时是否显示控制台窗口，一般设置为true显示控制台  
            "MIMode": "gdb",  
            "miDebuggerPath": "D:\softwares\coding\mingw-w64\x86_64-8.1.0-release-posix-seh-rt_v6-rev0\mingw64\bin\gdb.exe", // miDebugger的路径，注意这里要与MinGw的路径对应  
            "preLaunchTask": "g++", // 调试会话开始前执行的任务，一般为编译程序，c++为g++, c为gcc  
            "setupCommands": [  
                {   
		    "description": "Enable pretty-printing for gdb",  
                    "text": "-enable-pretty-printing",  
                    "ignoreFailures": true  
                }  
            ]  
        }  
    ]  
}

另外一个，其实大同小异，只需要替换两个文件中g++.exe和gdb.exe的位置即可，注意tasks中的lable和launch中的preLaunchTask要一致。
