1.下載VSCode

下載地址

2.安裝插件

插件1.png

插件2.png

3.打開一個(gè)包含C/C++文件的目錄

沒有，可以自己創(chuàng)建一個(gè)cpp文件

cpp.png

4.command+shift+p打開命令行工具窗口

命令行窗口.png

配置c_cpp_properties.json文件
選擇C/Cpp: Edit Configurations命令
此時(shí)會(huì)在當(dāng)前工作空間目錄生成.vscode配置目錄
同時(shí)在配置目錄會(huì)生成一個(gè)c_cpp_properties.json文件

"name": "Mac",
"includePath": [
            "${workspaceFolder}",
            "/Library/Developer/CommandLineTools/usr/include/c++/v1",
            "/usr/local/include",
            "/Library/Developer/CommandLineTools/usr/lib/clang/9.0.0/include",
            "/Library/Developer/CommandLineTools/usr/include",
            "/usr/include"
        ],

將要用到的庫的路徑添加到includePath數(shù)組中

配置tasks.json文件
選擇Tasks: Configure Task命令
此時(shí)會(huì)在配置目錄生成一個(gè)tasks.json文件

{
  // See https://go.microsoft.com/fwlink/?LinkId=733558
  // for the documentation about the tasks.json format
  "version": "2.0.0",
  "tasks": [
    {
        "label": "echo",
        "type": "shell",
        "command": "echo Hello"
    }
  ]
}

修改該配置文件如下

 "tasks": [
    {
        "label": "c++",
        "command": "clang++",
        "type": "shell",
        "args": [
            "hello.cpp",
            "-std=c++11",
            "-g"
        ],
        "presentation": {
            "echo": true,
            "reveal": "always",
            "focus": false,
            "panel": "shared"
        }
    }
]

該文件其實(shí)就是一個(gè)命令行構(gòu)建工具
把運(yùn)行程序時(shí)在終端輸入的命令和參數(shù)對(duì)于"command"和"args"的值
輸入shift+command+b，便可構(gòu)建成功，生成可執(zhí)行文件a.out

配置launch.json文件
選擇Debug: Open launch.json命令
此時(shí)會(huì)在配置目錄生成一個(gè)launch.json文件

{
// 使用 IntelliSense 了解相關(guān)屬性。 
// 懸停以查看現(xiàn)有屬性的描述。
// 欲了解更多信息，請(qǐng)?jiān)L問: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
    {
        "name": "(lldb) Launch",
        "type": "cppdbg",
        "request": "launch",
        "program": "enter program name, for example ${workspaceFolder}/a.out",
        "args": [],
        "stopAtEntry": false,
        "cwd": "${workspaceFolder}",
        "environment": [],
        "externalConsole": true,
        "MIMode": "lldb"
    }
  ]
}

修改文件如下

 "configurations": [
    {
        "name": "c/c++ Launch",
        "type": "cppdbg",
        "request": "launch",
        "program": "${workspaceFolder}/a.out",
        "args": [],
        "stopAtEntry": false,
        "cwd": "${workspaceFolder}",
        "environment": [],
        "externalConsole": true,
        "MIMode": "lldb",
        "preLaunchTask":"c++"
    }
]

preLaunchTask后面配置的是task的label，作用是當(dāng)源代碼發(fā)生改變時(shí)，啟動(dòng)調(diào)試會(huì)自動(dòng)編譯，而不用主動(dòng)輸入shift+command+b進(jìn)行編譯
該文件是一個(gè)配置調(diào)試的文件

json文件說明
上述3個(gè)文件需要做一定的修改

5. 開啟調(diào)試

調(diào)試視圖.png

修改hello.cpp

#include<stdio.h>

int
main()
{
   printf("Hello World\nWelcome to go to C++\n");
}

點(diǎn)擊調(diào)試漢字旁邊的綠色小三角，就會(huì)出現(xiàn)執(zhí)行結(jié)果

執(zhí)行結(jié)果.png

至此一個(gè)簡單的c/c++程序就完成了從編寫到執(zhí)行的過程
