Print Reverse of a string using Recursion

Print reverse of a  string using recursion:

# include <stdio.h>

/* Function to print reverse of the passed string */
void reverse(char *str)
{
   if(*str)
   {
       reverse(str+1);
       printf("%c", *str);
   }
}

int main() 
{
   char a[] = "Tech Stuff for Interview";
   reverse(a);
   return 0;
}

Explanation: Recursive function (reverse) takes string pointer (str) as input and calls itself with next location to passed pointer (str+1). Recursion continues this way, when pointer reaches ‘\0′, all functions accumulated in stack print char at passed location (str) and return one by one.
