Class is a user-defined data type in C++. It can be created to solve a particular kind of problem. After creation the user need not know the specifics of the working of a class.
Class is a User Defined Data Type....it encapsulate both data and functions.Real time Example: Car is a class....under which we have different types which is called a object interms of OOP.Software Ex: if i declare variable say int a; .....here int is CLASS. and a is obeject of int class.
Class is a data structure which is used to store variables and functions together. For example House is a class which consists of several components like the Bathroom Dining hall kitchen and etc

A class is a user-defined data type that encapsulates data and methods that can act upon the data together.
A class can also be defined as a classification/category of objects that have similar attributes and behaviour. For example Automobile is a category of objects that have similar attributes such as wheels engine doors shape color cylinders etc. and behaviours such as start run move turn etc. Car is an instance of automobile which has different values for the attributes (4 wheels one engine 2 or 4 doors 4/6/8 cylinders etc) whereas a semi-truck is another instance of automobile that has different values for the same attributes (18 wheels one engine two doors and so forth).
A class is a User Defined Datatype which acts as a Model. Means we can create objects with that Class(model). Its a collection of datamembers and Memberfunction.
Class is a data type .Class is a blue print of objects. Class gives an opportunity to define his on class according to his problem rather than using existing data type like float char e.t.c.
