/*
 Define a class named Student with the following properties:
Data members – 
	Name
	Roll
	Marks in CA1, CA2, CA3, CA4, PCA1 and PCA2
Member functions –
	To calculate Total of all CA marks, Total of all PCA marks, Overall Total marks and Overall percentage.
	Display the values
Take values of 5 students using array of objects and display the values one by one.
