C++ Exercises: Create a new string taking the first 3 characters of a given string and return the string with the 3 characters added at both the front and back

C++ Basic Algorithm: Exercise-11 with Solution

Write a C++ program to create a new string taking the first 3 characters of a given string and return the string with the 3 characters added at both the front and back. If the given string length is less than 3, use whatever characters are there.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

string  test(string str)
        {
             if (str.length() < 3)
            {
                return str + str + str;
            }
            else
            {
                string front = str.substr(0, 3);
                return front + str + front;
            }
        }
        
int main() 
 {
  cout << test("Python") << endl;  
  cout << test("JS") << endl;  
  cout << test("Code") << endl;  
  return 0;    
}

Sample Output:

PytPythonPyt
JSJSJS
CodCodeCod
