Question

C++

Write a recursive function that reverses the given input string. No loops allowed, only use recursive functions.
Do not add more or change the parameters to the original function. Do not change the main program.

#include <iostream>
#include <string>
using namespace std;

//Write a recursive function 'void reverse(string &str)' that reverses the given input string.
void reverse(string &str)
{
/*Code needed*/
}

int main()
{

   string name = "sherry";
   reverse(name);
   cout << name << endl; //should display "yrrehs"
   return 0;

}

Answer:

Code:

#include <iostream>
#include <string>
using namespace std;


//Write a recursive function 'void reverse(string &str)' that reverses the given input string.
void reverse(string &str)
{

if ((str==null)||(str.length() <= 1))

           System.out.println(str);

        else

        {

            System.out.print(str.charAt(str.length()-1));

            reverse(str.substring(0,str.length()-1));

        }

}

int main()
{

   string name = "sherry";
   reverse(name);
   cout << name << endl; //should display "yrrehs"
   return 0;

}
