What is the purpose of casting in C++?

In C++, casting is used to convert one data type to another. It allows programmers to explicitly convert data types when needed, ensuring the correctness of the program and avoiding potential type errors.

There are four types of casts in C++: static_cast, dynamic_cast, const_cast, and reinterpret_cast. Each type of cast has its own specific purpose and limitations. For example, static_cast is used for converting basic types, dynamic_cast is used for polymorphic types, const_cast is used for removing const qualifiers, and reinterpret_cast is used for converting one pointer type to another.

In general, cast in C++ is a very useful tool that can help programmers with converting between data types, improving the flexibility and reliability of the program.
