Following is one way to reverse string using recursion!
#include <stdio.h>
#include <string.h>
void rev_str_recursive(char arr[], size_t iStart, size_t iLast)
{
if( iStart < iLast )
{
//swap
char temp = arr[iStart];
arr[iStart] = arr[iLast];
arr[iLast] = temp;
rev_str_recursive(arr, ++iStart, --iLast);
}
}
void main()
{
char cArray[] = {"A quick brown fox jumps over a lazy dog"};
rev_str_recursive(cArray, 0, strlen(cArray)-1);
}

You need to modify the string, i.e. the input buffer to reverse(), instead of just printing it.
Doing this recursively seems a bit obnoxious, but should of course be possible.
Basically, I guess the printing becomes an assignment, something like this:
- Base: The reversal of an empty string is the empty string.
- Step: The reversal of a string begins by swapping the first and last characters, then recursing over the remainder of the string.

C Program: Get reverse of a string - w3resource
This recursively moves through the string until it reaches the end. For each recursive call, the function stores the current character at the i-th index of the ‘revstr ‘ array and increments the i variable. Finally, when the first character is null, the function returns the revstr array which contains the reversed string.
