Swapping Private data of classes

 CASE 1: 

Given two numbers a & b, swap these two numbers using the friend function of C++. 

Examples: 

Input : a = 5, b = 9
Output : a = 9, b = 5

Input : a = 4, b = 6
Output : a= 6, b = 4
  • Approach: 
  • Create a class Swap, declare one variable in it, i.e., num, and create a constructor for inputs. Declare a friend function in it. Define the friend function outside the class scope by taking arguments as call by reference to pass the copy of Swap Object. Perform the swap operation.
