    else

    menu(tecla);

    Sleep(40);
}


system("pause>null");

return 0;
}

What I want to get to do is something like this

You could also use the ANSI escape codes link (The English version is more complete)

But it is important to indicate that the support may vary depending on the terminal used.

The sequence must start with an escape character

  

ESC [... 38; 2 ;;; ... m Text Color

     

ESC [... 48; 2 ;;; ... m Background Color

You can combine the text color with a background and print them

For example, the following code will print a text with a yellow background and red letters, the last [0m open leaves the terminal as it was. 

printf("\x1b[0;31;43mhello world\x1b[0m");

Where 31 is the text color (Red) and 43 the background color (Yellow)

I leave the table of equivalences

You can define the color using the system function

  

system ("color * background ** foreground *");

Where background and foreground can contain values between 0-9 and A-Z

The following code prints a text with a blue background and green text 

system("color A1");
std::cout<<"Hello World"<<std::ends;

To see all the color options run 

system("color %");
