C++ Exercises: Create a new string with the last char added at the front and back of a given string of length 1 or more

C++ Basic Algorithm: Exercise-9 with Solution

Write a C++ program to create a string with the last character added at the front and back of a given string of length 1 or more.

Sample Solution:

C++ Code :

#include <iostream>
using namespace std;

string test(string str)
        {
            string s = str.substr(str.length()-1);
            return s + str + s;
        }
        
int main() 
 {
  cout << test("Red") << endl;  
  cout << test("Green") << endl;  
  cout << test("1") << endl;  
  return 0;    
}

Sample Output:

dRedd
nGreenn
111

Previous: Write a C++ program to create a new string which is 4 copies of the 2 front characters of a given string. If the given string length is less than 2 return the original string.
Next: Write a C++ program to check if a given positive number is a multiple of 3 or a multiple of 7.

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 )
