C++ is a programming language that was first developed by Bjarne Stroustrup in 1983. It is a general-purpose programming language that is widely used for a variety of applications, including system programming, game development, and enterprise software.HistoryC++ was originally designed as an extension to the C programming language, which was created in the early 1970s. C++ added object-oriented programming features to C, including classes, objects, and inheritance. The first version of C++ was released in 1985.FeaturesC++ is a statically typed language that supports both procedural and object-oriented programming. It has a rich set of built-in data types, including integers, floating-point numbers, characters, and strings. It also supports user-defined data types using classes and structs.C++ provides a variety of control structures, including if-else statements, switch statements, for loops, while loops, and do-while loops. It also supports recursion and goto statements.C++ includes a large set of functions and libraries that provide access to system-level functionality, including file I/O, network programming, and process control. It also includes a large set of standard libraries that provide classes and functions for common tasks, such as containers, iterators, algorithms, and string manipulation.Object-Oriented Programming in C++C++ provides support for object-oriented programming using classes and objects. Classes are user-defined data types that contain data members and function members. Objects are instances of classes that can be created and used to perform operations. Classes can be inherited from other classes using the class keyword and the : : operator. Inheritance allows new classes to be created from existing classes and to add or override methods and properties.Example CodeHere is an example of C++ code that demonstrates a simple program to print the message "Hello, World!" to the console:In this example, the #include directive includes the <iostream> header file, which provides input/output functionality. The main() function is the entry point of the program, and it returns an integer value of 0 to indicate successful execution. The std::cout object is used to output messages to the console, and in this case it prints the string "Hello, World!" followed by a newline character (std::endl).
