Converting RGB to Hex.

Hi again folks,

Currently I am trying to make a program that will give the hexadecimal value of a colour based upon the RGB values. This is the code that I have:

Code:

---

/* RGBtoHEX - A program designed to convert colours in RGB to Hexadecimal value */
#include <stdio.h>

main()
{
      int red;
      int green;
      int blue;
     
      printf("Please enter the value for Red: ");                                         
      scanf("%d",&red);
      printf("Please enter the value for Green: ");
      scanf("%d", &green);
      printf("Please enter the value for Blue: ");
      scanf("%d", &blue);
     
      printf("\nThe hexadecimal value for your colour is #%X%X%X.", red, green, blue); 
     
      return 0;
}

---

Currently, the line

Code:

---

printf("\nThe hexadecimal value for your colour is #%X%X%X.", red, green, blue);

---

,

will only correctly work for high values of R, G and B. I would like to know if you can transform, for example F to 0F, just for clarity in the output.

Any help is greatly appreciated,

Would "%02X" not work?

Thanks.

I take it if i were to put.

%03X or %04X it would display like 3 and 4 characters,

Thanks anyway and thanks in advance,
