Lesson 9
Classes and Objects
Classes and objects are the foundation of object-oriented programming in C++. They help organize data and behavior together.
Example
Example
#include <iostream>
#include <string>
using namespace std;
class Student
{
public:
string name;
int age;
void display()
{
cout << "Name: " << name << endl;
cout << "Age: " << age << endl;
}
};
int main()
{
Student s1;
s1.name = "Alice";
s1.age = 20;
s1.display();
return 0;
