/*Question 2 . Accept any two numbers from the user.
Perform the following operations on it using functions:
1. Addition
2. Subtraction
3. Multiplication
4. Swap the values
5. Print both the numbers in reverse order for example (if a
given number is 234, it should
be printed as 432)
CONCEPT : Using SWITCH statement and functions
SYNTAX : switch
{
case 1: statements;
Break;
case 2: statements;
Break;
…
default: statements;
