C program to Print hex values of characters in string

Following program prints the hexadecimal values of all the characters in any string. Currently we have used a static string for the demonestration, but you can write your own function to print hex values by passing string as input argument to the function for the debugging purpose and call that function as and when necessary.

#include <stdio.h>
#include <string.h>

int main(int argc, char **argv) {
        unsigned char any_string[] = "helloworld";
        int i;

        for (i=0; i < strlen(any_string); i++ )
                printf("%2x ",any_string[i] & 0xff);

        return 0;
