Why do we use classes and objects in programming?

Classes are used to create and manage new objects and support inheritance—a key ingredient in object-oriented programming and a mechanism of reusing code.

What is an object in programming?

In object-oriented programming (OOP), objects are the things you think about first in designing a program and they are also the units of code that are eventually derived from the process. Each object is an instance of a particular class or subclass with the class’s own methods or procedures and data variables.

A class is a user-defined blueprint or prototype from which objects are created. Classes provide a means of bundling data and functionality together. Creating a new class creates a new type of object, allowing new instances of that type to be made.

To cast an object to another class, you use the same operation as for primitive types: In this case, classname is the name of the destination class, and object is a reference to the source object. Note that casting creates a reference to the old object of the type classname; the old object continues to exist as it did before.

What are the types of type conversions in C programming?

Casting and type conversions (C# Programming Guide) 1 Implicit conversions. For built-in numeric types, an implicit conversion can be made when the value to be stored can fit into the variable without being truncated or rounded off. 2 Explicit conversions. 3 Type conversion exceptions at run time. 4 C# language specification. 5 See also
