hex to dec in c

I have a question, does anybody know about a function in C that will convert a char string like '2C' into a decimal number.

Thanks.

sscanf it in as a hex and sprintf it out as a dec.

sscanf() or strtol(), take your pick.

Code:

---

#include <stdlib.h>
#include <stdio.h>
.
.
  int num;
 
  if (sscanf("2C", "&#37;X", &num) != 1)
  {
      printf("Error during conversion.\n");
      return EXIT_FAILURE;
  }

An easier method is to use "strtol". It allows you to use any base you like, up to (I think) 36.

Edit: Swoopy beat me to it.
