Set the color of printf output font in terminal

The color of the terminal character is controlled by the escape sequence, which is the system display function in the text mode, regardless of the specific language.
The escape sequence starts with the ESC and can do the same with \033 (the ASCII code for ESC is in decimal notation is 27, = 33 in octal).

A) format is:

\033[display mode; foreground color; background colour m

1) display mode: 0 (default), 1 (highlighted), 22 (not bold), 4 (underscore), 24 (non-underlined), 5 (blinking), 25 (non-flashing), 7 (inverted), 27 (non-inverting)
2) Foreground: 30 (Black), 31 (red), 32 (green), 33 (yellow), 34 (blue), 35 (magenta), 36 (cyan), 37 (white)
3) Background color: 40 (Black), 41 (red), 42 (green), 43 (yellow), 44 (blue), 45 (magenta), 46 (cyan), 47 (white)

II) Examples:

1) Default color: \033[0m
2) Green: \033[1;32;40m
3) Red: \033[1;31;40m

4) printf ("\033[1;31;40m output red character \033[0m")
