VSCode編寫C/C++項目

VSCode編寫C/C++項目

1. 下載插件C/C++、C++ Intellisense;
2. 新建一個空文件夾，從VSCode打開。 (或File-->Open Folder-->新建一個空文件jia);
3. 按F5（用命令行gcc、g++；或者編寫makefile文件，make；），選擇C++(GDB/LLDB)，生成launch.json（用來調試）;
5. 修改launch.json，將"program": "enter program name, for example ${workspaceFolder}/a.out"改為"program": "${workspaceFolder}/ProjectName";
"externalConsole": true，表示輸出會在彈出的命令行。修改為false的化，會在VSCode內部terminal輸出。
6. Ctrl+Shift+B, 選擇tasks.json-->模板--->other，生成tasks.json（創建任務）；
7. 修改 tasks.json， "command": "echo Hello"改成"command": "g++ -o ProjectName ProjectName.cpp"，這里的ProjectName和5中的ProjectName同名
8. 對於復雜的項目，"command": "echo Hello"改成"command": "make"
9. 再創建makefile文件，編輯；
10. 編寫Hello.cpp文件
11. 按Ctrl+Shift+P, 選擇 Task:Run Tasks，執行任務
12. 按F5，執行

源代碼如下所示：

Hello.cpp

#include <iostream>
using namespace std;
int main()
{
    cout << "Hello, world!" << endl;
    return 0;
}

launch.json

{

                    "ignoreFailures": true
                }
            ]
        }
    ]
}

tasks.json

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558

        }
    ]
}

makefile或Makefile
