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 )
