C++ Exercises: Create a new string using first two characters of a given string

C++ Basic Algorithm: Exercise-60 with Solution

Write a C++ program to create a new string using first two characters of a given string. If the string length is less than 2 then return the original string.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

string test(string s1)
         {
            return s1.length() < 2 ? s1 : s1.substr(0, 2);
         }
         
int main() 
 {
  cout << test("Hello") << endl;  
  cout << test("Hi") << endl;  
  cout << test("H") << endl;  
  cout << test(" ") << endl;    
  return 0;    
}

Sample Output:

He
Hi
H
