1. added swapping of two integers in c++ …

   This C++ program is designed to swap the values of two user-input integers using a dedicated swap function. Here’s a detailed breakdown of the program:
   
   Program Structure:
   Headers and Namespace:
   
   The program includes the iostream header to handle input/output operations and uses the std namespace to avoid prefixing std:: before standard library functions like cin and cout.
   Swap Function:
   
   The swap function is defined to take two integer references (int &a and int &b) as parameters. By passing by reference, the original values of a and b are swapped inside the function. The function works by:
   Storing the value of a in a temporary variable temp.
   Assigning the value of b to a.
   Assigning the value of temp (original a) to b.
   This effectively swaps the values of the two integers without returning anything.
   Main Function:
   
   The main function starts by declaring two integers, a and b, to hold the numbers input by the user.
   It prompts the user to input the first and second numbers, storing them in a and b respectively.
   The values of a and b are displayed before the swap operation.
   The swap function is then called to interchange the values of a and b.
   After the swap operation, the updated values of a and b are printed to show the successful swapping of numbers.
