C Program to Reverse the String using Recursion

C Program :

	/* Aim: Write a function which displays a string in reverse order (Use Recursion)*/
	#include<stdio.h>
	#include<string.h>
	#define size 100
	void re_StrRev(char str[],int i); // re_StrRev Function Prototype
	void main()
	{
	char str[size];
	printf("\n Enter any string:-");
	scanf("%s",str);
	printf("\n");
	re_StrRev(str,strlen(str)-1);
	printf("\n \n");
	} // End of main
	// re_StrRev Function
	void re_StrRev(char str[],int i)
	{
	if(i>=0)
	{
	printf("%c",str[i]);
	re_StrRev(str,i-1);
	}
	} // End of re_StrRev Function
	/* Ouput of above code:-
