In C++ what is the difference between an object and a class? I'm confused, is an object always a class?
In C++, a class is a blueprint or template for creating objects, while an object is an instance of a class. A class defines the properties and behaviors of objects, while objects are concrete entities that can be created and manipulated in a program.
Classes and objects are closely related in C++. A class serves as a template for creating objects, and objects are created using the blueprint provided by a class. Changes made to a class will affect all objects created from it, but each object has its own unique set of properties and behaviors.
Yes, a class can have multiple objects in C++. Each object is created using the same class structure but can have different values for its properties. This allows for efficient and organized data management in a program.
In C++, a class is declared using the keyword "class" followed by the class name. Objects are declared using the class name followed by parentheses and a semicolon. For example: class MyClass { // class declaration }; MyClass myObject; // object declaration
Constructors are special functions within a class that are used to initialize objects when they are created. They have the same name as the class and are automatically called when an object is created. Constructors can also be used to set default values for object properties.
