C++ Exercises: Create a new string using 3 copies of the first 2 characters of a given string

C++ Basic Algorithm: Exercise-77 with Solution

Write a C++ program to create a new string using 3 copies of the first 2 characters of a given string. If the length of the given string is less than 2 use the whole string.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

string test(string s1)
          {
            string extra_Front = "";
  
            if (s1.length() < 2)
            {
                return s1 + s1 + s1;
            }
            else
            {
                extra_Front = s1.substr(0, 2);
                return extra_Front + extra_Front + extra_Front;
            }
        }
        
int main() 
 {
  cout << test("abc") << endl;  
  cout << test("Python") << endl; 
  cout << test("J") << endl;  
  return 0;    
}

Sample Output:

ababab
PyPyPy
JJJ

Previous: Write a C++ program to concat two given strings. If the given strings have different length remove the characters from the longer string.
Next: Write a C++ program to create a new string from a given string. If the two characters of the given string from its beginning and end are same return the given string without the first two characters otherwise return the original string.
