Since visual studio code is just a source code editor for multiple language including C++. We need below things to setup a good C++ dev environment.
- Install VS Code for windows
- C++ specific formatter which helps while we write code. VS code provides various extensions to help in this such as C/C++ Extensions by Microsoft
- C++ Compiler(such as mingw) to be used for code compilation
Go to VS Code download page and download vscode for Windows and install by double clicking the downloaded installer and following installation steps.
Please do check if MINGW is already installed on your system by running
g++ --verison on PowerShell or Command prompt and verify
-> Dont look it in 'Program Files' folder since generally MINGW is installed using copy/paste way and it is copied in C:\MINGW or similar. Even if it is installed using installer it copies at C:\MINGW only. You can also check environment path where it might have been added if it was installed earlier
Now we have editor and compiler, let us write our code, compile, debug and run.
VS Code provides various extensions to help with intelligence, indentation, static analysis, formatting etc.
You can open visual studio code extension using [ctrl + shift + x] or View->Extensions. Just for begining, Search for C/C++ extension from Microsoft and install it from vs code itself.
Go to Command Pallete (Ctrl + Shift + P) and select C/C++: Edit Configurations to Add dependent includePath and library path in C_CPP_Properties.json
Go to Command Pallete (Ctrl + Shift + P) and select Task: Configure Task to create/modify task.json to configure compiler path, command etc
Go to Run and Debug in left side bar (Ctrl + Shift + D) and configure program to run and other dependencies by editing launch.json
Please note above build/launch would be created for selected file only therefore make sure .cpp is selected. Also you can compile/run the code using g++ compilation command such as g++ -g -o and run from command line
Go to MINGW download page and download vscode for Windows and install by double clicking the downloaded installer and following installation steps. which will copy mingw installation files at C:\MINGW or C:\MINGW64. Add it to PATH by editing environment variables.
