18CSC202J – Object Oriented Design and Programming




1. Create a class named 'Student' with a string variable 'name' and an integer variable
'roll_no'. Assign the value of roll_no as '2' and that of name as "John" by creating an
object of the class Student.
ANS-
PROGRAM:

#include <iostream>
#include <string>
using namespace std;


class student {
public:
string name;
int roll_no;
};


int main() {
student st1;


st1.name = "john";
st1.roll_no = 2;


cout << "Name: " << st1.name << endl;
cout << "roll: " << st1.roll_no << endl;
}

, 2. Write a C++ program to illustrate the concept of class and object creation. (Ask
students to create a class, methods and invoke them inside the main method).
ANS-
PROGRAM:

#include <bits/stdc++.h>
using namespace std;
class Geeks
{
// Access specifier
public:


// Data Members
string geekname;


// Member Functions()
void printname()
{
cout << "Geekname is: " << geekname;
}
};


int main() {


// Declare an object of class geeks
Geeks obj1;


// accessing data member
obj1.geekname = "sakshi";


// accessing member function
