C++ program to concatenate a string given number of times

Write a function which returns a new string which is made by concatenating a given string n number of times.

Examples:

Input : str = "geeks"
         n  = 3
Output : str = "geeksgeeksgeeks"
We concatenate "geeks" 3 times

Input : str = "for"
         n  = 2
Output : str = "forfor"
We concatenate "for" 2 times
