Unix-based System

To execute a C++ console program in background mode on a Unix-based system, you can use the “nohup” command. The syntax is as follows:

nohup ./your_program &

The “nohup” command allows the program to continue running after you close the terminal window. The “&” at the end of the command runs the program in the background.

screen
./your_program
ctrl+a+d

This will run your program in detached mode, so you can close the terminal, and it will still be running.

You can check the status of the program by running “ps aux | grep your_program”. You can also check the output of the program by running “tail -f nohup.out”

Windows

On Windows, you can use the “start” command to run a program in the background. The syntax is as follows:

start /B your_program.exe

This will open the program in a new window, but it will not be in the foreground. The “/B” option specifies that the new process should be run in the background.

To set the program as a default background program, you need to create a shortcut of the program and put it in the startup folder. You can do this by:

1. Locate the program executable, right-click it and select “Create Shortcut”.
2. Right-click the shortcut, and select “Properties”
3. In the “Target” field, add “start /B” before the path of the program.
4. Press “Apply” and “OK”
5. Drag the shortcut to the startup folder.

You can also do this by navigating to the startup folder:

C:\Users\YourUserName\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

After that, the program will automatically start in the background every time the computer is rebooted.
