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

C++ Basic Algorithm: Exercise-63 with Solution

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>
using namespace std;

string test(string s1, string s2)
         {
             return s1.length() < s2.length() ? s2 + s1 + s2 : s1 + s2 + s1;
         }
         
int main() 
 {
  cout << test("Hello", "Hi") << endl;  
  cout << test("JS", "Python") << endl; 
  return 0;    
}

Sample Output:

HelloHiHello
PythonJSPython

C++ Programming: Tips of the Day

What is the "-->" operator in C/C++?

--> is not an operator. It is in fact two separate operators, -- and >.

The conditional's code decrements x, while returning x's original (not decremented) value, and then compares the original value with 0 using the > operator.

To better understand, the statement could be written as follows:

while( (x--) > 0 )
