C++ can be used in developing browsers, operating systems and applications as well as in game programming, software engineering, data structures etc.

While learning C++ start with C++ basics which includes comments, tokens, identifiers, structure of code then learn variables, data types, operators, functions, pointer, arrays & strings, structure & unions, object-oriented programming, encapsulation and abstraction, polymorphism, Inheritance.

Objects and classes are used to wrap related functions in data in one place in C ++. Is a blueprint for the object. A class in C++ is defined using the keyboard class followed by the name of the class. To use the data and access functions defined in the class, we create objects. For example: “class TNP”.

TNP Officer provides lots of mock tests to practice. You can find and practice a free C++ programming mock test at www.tnpofficer.com.
