In this tutorial, we will write a Program to Reverse a String in C++ using recursion. Before beginning, you must be familiar with the following topics in C++.

Recursion refers to the process when a function calls itself inside that function directly or indirectly or in a cycle.

C++ Program to Reverse a String using Recursion

#include <iostream>
using namespace std;

void reverseFunc(char *str); //function prototype

//main function
int main()
{
  char str[] = "This is simple2code.com";

  cout << "Actual String: " << str << endl;
  cout << "\nReversed String: ";

  reverseFunc(str);

  return 0;
}

//recursion function
void reverseFunc(char *str)
{
  if (*str == '\0')  //base condition
  {
    return;
  }
  else
  {
    reverseFunc(str + 1);
    cout << *str;
  }
}

Output:

Actual String: This is simple2code.com

Reversed String: moc.edoc2elpmis si sihT

You may go through the following program on a string.
