The relationship between Class and Object

Exactly, you got the idea right. Let me explain it:

The Class (the category / classification): it's the template or blueprint. When you say Student, Course, or Employee, you are creating a classification — you define a type of thing along with its properties and behavior, but it's just an idea/template, not a real thing existing in memory.

The Object (the instance): it's a real instance of the class, actually existing in memory and having values.

An example to show the difference:

class Student      // ← Class: the classification / the template
{
public:
    string Name;
    int Age;
    string Major;
};

int main()
{
    Student Student1;          // ← Object: a real object
    Student1.Name = "Ahmed";
    Student1.Age = 20;
    Student1.Major = "CS";

    Student Student2;          // ← Another Object from the same Class
    Student2.Name = "Sara";
    Student2.Age = 22;
    Student2.Major = "IT";
}

A simple analogy:

• Student = the word "student" in a dictionary (a general concept).
• Student1 and Student2 = Ahmed and Sara (real people, each one with their own data).

So the words you wrote (Student, Course, Doctor, Employee, Major, College, Department...) are all classes — classifications. And when you create actual instances from them with values, those instances become objects.

An important point: from a single class you can create an unlimited number of objects, and each object is independent in its values from the others.
