C++ Exercises: Create a new string from two given string one is shorter and another is longer

C++ Basic Algorithm: Exercise-63 with Solution

Long+Short+Long String Combination

Write a C++ program to create a new string from two given strings, one of which is shorter and the other is larger. The format of the updated string will be long string + short string + long string.

Sample Solution:

C++ Code :

#include <iostream> // Including the input/output stream library

using namespace std; // Using the standard namespace

// Function that concatenates strings based on their lengths
string test(string s1, string s2)
{
    // Conditional operator to determine which string concatenation to perform
    return s1.length() < s2.length() ? s2 + s1 + s2 : s1 + s2 + s1;
}

// Main function
int main() 
{
    cout << test("Hello", "Hi") << endl;  // Output the result of test function with "Hello" and "Hi"
    cout << test("JS", "Python") << endl; // Output the result of test function with "JS" and "Python"
    return 0;    // Return statement indicating successful termination of the program
}

Sample Output:

HelloHiHello
PythonJSPython
