Thread: hex to dec in c

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

>does anybody know about a function in C that will convert a char string like '2C' into a decimal number.
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;
   }
