Text Colors
Text color output is not defined in ANSI C/C++. Instead the creators of the language left that to be operating system dependent. In Linux, to change text color you must issue what are known as terminal commands. To do this you just change your output statement to contain a terminal command.
For example, see the below program.
#include <stdio.h>
int main()
{
printf("Hello, world! ");
}
To print "Hello, world.!" in red I would change the printf statement to read:
printf(" 33[22;31mHello, world!");
33[22;31m is the terminal command: it will not be output to the terminal, instead it issues a command that changes all proceeding output to be printed in red
All the colors that I have found are:
33[22;30m - black
33[22;31m - red
33[22;32m - green
33[22;33m - brown
33[22;34m - blue
33[22;35m - magenta
33[22;36m - cyan
33[22;37m - gray
33[01;30m - dark gray
33[01;31m - light red
33[01;32m - light green
33[01;33m - yellow
33[01;34m - light blue
33[01;35m - light magenta
33[01;36m - light cyan
33[01;37m - white
