RE: What is the Difference between Class and Instance
The Class is a blueprint which holds the code but the instance is the real object inside the memory so we can access its properties and methods in the Run-time.
RE: What is the Difference between Class and Instance
Class contains the declaration and definition of all of it member variables and the member functions along with their respective access specifiers. A Class remains same for all of it's objects or instances.
Object is a mere instantiation of a class. All the member variables and the member functions of a class are used via the object except the static ones. For every instance/object created of a class a different set of member variables and function references is created. Thus each object has it's own set of member variables. when a function of a class is called on an object of that class what all changes/operations/updations are done are specific to that object. Static member variables and static functions are exceptions to this.
