Program 2

/* PROGRAM - 2

 Define a class Student with the following members:



Private members :

rollno, name, marks[5] and stream.

Assignstream ( ) - to assign stream according to the condition given below

If percentage > = 95,       stream =Electronics
If percentage >=80 & < 95 ,        =Computer Science
If percentage >=60 & < 80 ,        =Civil
Otherwise - Not allotted

Public Members :

void  getstud ( )     -        to input data members except stream.

Void putstud ( )    -        to display all data members.

Write a program to implement this class for an array of 3 students.*/
