More features below

• Open a .cpp file and you will see outputs beside cout and identifier statements.
• Automatically starts on .cpp files (For Manual Activation, Read Next Section)
• Input must come from txt files or buffer. (See Below (Input/Output))

• Mode: Status bar item 🌐/💻 indicates whether cloud compiler or local compiler (g++ command) is being used

• Format: alt+shift+f to format the file. (Gets set as cpp formatter by default after installation, if you have multiple formatter extensions, you can change it in settings or in command palette type Format Document With...)

• Visualization: From Command Palette, search C++ Playground: then visualize

• Others: Access other features from Command Palette: Ctrl+Shift+P or F1 and search C++ Playground: then format,input,mode,start,etc

• Activation/Deactivation:

  • Activate manually: ctrl+alt+shift+n (Activated automatically on .cpp files)
  • Deactivate manually: ctrl+alt+shift+q
  • Click status bar item saying CPP REPL to toggle between active and deactive state with a .cpp file open
  

• You will need computation power to use the extension.

• Input statements like cin and scanf must be removed or hardcoded or stream must be altered (Or else you will get timeout after 10s).
• Stream Alteration Example 1:

int main(){
    freopen("input.txt", "r", stdin);
    int x; std::cin >> x; // reads int from input.txt file
    std::cout << x + 1;
}

• Example 2:

#include<sstream>
int main() {
    std::istringstream iss(R"(
        3 line
        input 
        example
    )");
    std::cin.rdbuf(iss.rdbuf()); // done
    int x; std::cin >> x; // stores 3
    std::cout << x + 1; // 4
}

• You can also type Ctrl+Shift+P or F1 to open the command palette and search for Insert Input Hardcode Template to automatically insert the hardcoded input at the start of main function.

• Open VSCode Extension tab (Shortcut: ctrl+shift+X) and type 'cpp repl'
• Install the extension named C++ Playground: Inline REPL + Bla Bla Bla

• If you have any feature requests, feel free to join Discord (CodePlayground) or email me.

• Zero Configuration
• Executes the code as you type and shows outputs beside each line
• Prints complex data structures in pretty format
• Format code with AStyle
• Visualize runtime code execution in realtime
• Lints errors beside defective lines
• Shows compiled output in a separate panel (Can be turned off)
• Makes it easier to debug and view values of variables from within editor
• Can run using both cloud and local compilations (g++ for local as of now)
• Lightweight and as fast as it gets

• If you use cloud compiler (default), it requires internet obvisously.
• Else if you're on offline mode (switch using status bar icon), it will require C++ compiler (g++) to be installed on your pc beforehand.
• (On Cloud Mode) Compatible with code that use C++14 or below version (currently on servers) (might vary from time to time)
• (On Local Mode) Compatible with code that use the g++ version that you have.

• [Easiest] To install gcc (includes g++) on windows run (in powershell): With Scoop:

  Set-ExecutionPolicy Bypass -Scope Process -Force;
  iex "& {$(irm get.scoop.sh)} -RunAsAdmin"; scoop install gcc

  OR with Chocolatey:

  Set-ExecutionPolicy Bypass -Scope Process -Force;
  iwr -useb https://chocolatey.org/install.ps1 | iex; choco install mingw -y

• For Windows users, you can also use the Windows Subsystem for Linux to run C++ code
• Verify using

  g++ --version

• Status bar icon 🌐/💻 used to switch between cloud and local compiler mode.
• Delay after keystores: Look into settings.
• Auto open output panel: Look into settings.
