These are very helpful functions to change the color or the background of the text. How this works is first we got to set the color of the text and then print something on the console?

<conio.h> - textbackground() function in C

To use the textbackground() function all you need to do is before printing any text call this function with a parameter defining the color in capital letters. That will be enough to change the background color of the text.

textbackground() function Example in C

#include <stdio.h>
// to use 'textbackground'
#include <conio.h>

int main() {
  // setting the color of background
  textbackground(GREEN);

  // message
  cprintf("Change the background color to green");

  getch();
  return 0;
}

Output

<conio.h> - textcolor() function in C

Now, if you want your text to blink then while calling the textcolor() function pass the color and also say BLINK. This will like this: textcolor(BLUE+BLINK).

These are the function of the conio.h file and must be included in your program.

textcolor() function Example in C

#include <stdio.h>
// to use 'textcolor()'
#include <conio.h>

int main() {
  // set the color of text
  textcolor(BLUE);
  // message
  cprintf("Color of text is BLUE\n\n");

  // set blinking color
  textcolor(GREEN + BLINK);
  // message
  cprintf("\nThis is BLINKING text");

  getch();

  return 0;
}
