Exception Handling.cpp

/*Write a program(Use Class) with the following :

a) A function to read two double type numbers from keyboard
b) A function to calculate the division of these two numbers
c) A try block to throw an exception when a wrong type of data is keyed in
d) A try block to detect and throw an exception if the condition “divide - by - zero” occurs
e) Appropriate catch block to handle the exceptions thrown*/
