how to run cpp using gcc vscode

To run C++ code using GCC in Visual Studio Code (VSCode), you can follow these steps:

  1. Install GCC: First, ensure that you have GCC (GNU Compiler Collection) installed on your system. GCC is a compiler for C, C++, and other programming languages. You can install GCC by following the instructions specific to your operating system.

  2. Install VSCode: If you haven't already, download and install Visual Studio Code from the official website (https://code.visualstudio.com/). VSCode is a popular source code editor that provides a wide range of features and extensions.

  3. Open VSCode: Once you have installed VSCode, open it on your system.

  4. Create a new C++ file: In VSCode, open a new file by clicking on "File" in the menu bar, selecting "New File," and saving it with a .cpp extension (e.g., example.cpp).

  5. Write your C++ code: In the newly created file, write your C++ code. For example, you can write a simple "Hello, World!" program:

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

  1. Open the integrated terminal: To open the integrated terminal in VSCode, click on "View" in the menu bar, select "Terminal," and then click on "New Terminal." This will open a terminal window at the bottom of the VSCode interface.

  2. Compile the C++ code: In the terminal, use the g++ command followed by the name of your C++ file to compile it. For example, if your file is named example.cpp, you can use the following command:

g++ example.cpp -o example

This command tells the GCC compiler (g++) to compile example.cpp and produce an output file named example. The -o flag is used to specify the output file name.

  1. Run the compiled program: After successfully compiling the code, you can run the compiled program by entering its name in the terminal. For example, if your output file is named example, use the following command:
./example

This command runs the compiled program and displays the output on the terminal.

That's it! By following these steps, you can run C++ code using GCC in Visual Studio Code.
