c++ cmd program run in background

To run a C++ command-line program in the background, you can follow these steps:

1. Open a command prompt or terminal window.
2. Navigate to the directory where your C++ program is located using the cd command. For example, if your program is in a folder named "myprogram", you would type cd myprogram.
3. Compile your C++ program using a C++ compiler such as g++ or clang++. The command to compile a C++ program is typically g++ filename.cpp -o outputname, where filename.cpp is the name of your C++ source file and outputname is the desired name for the compiled executable file. For example, if your source file is named "myprogram.cpp" and you want the compiled executable to be named "myprogram", you would type g++ myprogram.cpp -o myprogram.
4. Once the compilation is successful, you can run the program in the background by appending an ampersand (&) to the command. For example, to run the program "myprogram" in the background, you would type ./myprogram &.

When you run the program in the background, it will continue to execute without blocking the command prompt or terminal window. You can continue to use the command prompt or terminal for other tasks while the program runs in the background.

Note that running a program in the background is specific to the command prompt or terminal you are using. Some terminals may have their own specific syntax or commands for running programs in the background. Make sure to consult the documentation or help resources for your specific command prompt or terminal if you encounter any issues.
