stdlib and colored output in C

All modern terminal emulators use ANSI escape codes to show colours and other things.
Don't bother with libraries, the code is really simple.

More info is here.

Example in C:

#include <stdio.h>#define ANSI_COLOR_RED     "\x1b[31m"#define ANSI_COLOR_GREEN   "\x1b[32m"#define ANSI_COLOR_YELLOW  "\x1b[33m"#define ANSI_COLOR_BLUE    "\x1b[34m"#define ANSI_COLOR_MAGENTA "\x1b[35m"#define ANSI_COLOR_CYAN    "\x1b[36m"#define ANSI_COLOR_RESET   "\x1b[0m"int main (int argc, char const *argv[]) {  printf(ANSI_COLOR_RED     "This text is RED!"     ANSI_COLOR_RESET "\n");  printf(ANSI_COLOR_GREEN   "This text is GREEN!"   ANSI_COLOR_RESET "\n");  printf(ANSI_COLOR_YELLOW  "This text is YELLOW!"  ANSI_COLOR_RESET "\n");  printf(ANSI_COLOR_BLUE    "This text is BLUE!"    ANSI_COLOR_RESET "\n");  printf(ANSI_COLOR_MAGENTA "This text is MAGENTA!" ANSI_COLOR_RESET "\n");  printf(ANSI_COLOR_CYAN    "This text is CYAN!"    ANSI_COLOR_RESET "\n");  return 0;}

Dealing with colour sequences can get messy and different systems might use different Colour Sequence Indicators.

I would suggest you try using ncurses. Other than colour, ncurses can do many other neat things with console UI.

You can output special color control codes to get colored terminal output, here's a good resource on how to print colors.

For example:

printf("\033[22;34mHello, world!\033[0m");  // shows a blue hello world

EDIT: My original one used prompt color codes, which doesn't work :( This one does (I tested it).
