notes_calculator.cpp

//This is a c++ program which will help you to calculate how many different notes will be required to pay a certain amount 
//This can be used by ATM to give money in different types of notes available inside it to give to the customer.

/*For Example:
To pay Rs.752 please use following notes: 
Number of 500 notes required is : 1  (500 X 1)
Number of 200 notes required is : 1  (200 X 1)
Number of  50 notes required is : 1  (50 X 1)
Number of  1  notes required is : 2  (1 X 2)
