Question

I have an integer returning from a function:

   int a = func();

For example, a = 236.

I need to treat this as a hexadecimal representation of an integer, and store its decimal representation in another variable, so that when printed like so:

  printf("%x", variable)

…the output should be:

 236

Answer 1

If i’ve understood what you need, this little code snippet will do it

#include <stdio.h>

int main()
{
    char num[128];
    int a=236;
    int hex;

    sprintf(num, "0x%d", a);

    sscanf(num, "%x", &hex);

    printf("Hex: %x\n", hex);
}

output is

Hex: 236
