What is classes and structure?

To create an object of Main , specify the class name, followed by the object name, and use the keyword new :

Structure is a user-defined data type that combines logically related data items of different data types, whereas Class is a blueprint or a set of instructions to build specific types of objects . Structure is a value type data type, whereas class is a reference type data type.

In programming, the struct is a keyword for creating a structure that contains variables, methods, different types of constructors, operators, etc . It is similar to classes that hold different types of data and has a value type. It creates objects which require less memory.2 Tem 2021
