C++ is a compiled, general-purpose, case-sensitive, free-form programming language that supports procedural, object-oriented, and generic programming. C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features. C++ was developed by Bjarne Stroustrup starting in 1979 at Bell Labs in Murray Hill, New Jersey, as an enhancement to the C language and originally named C with Classes but later it was renamed C++ in 1983. C++ is a superset of C, and that virtually any legal C program is a legal C++ program. Object-Oriented Programming C++ fully supports object-oriented programming, v  Encapsulation v  Data hiding v  Inheritance v  Polymorphism C++ Program Structure   #include <iostream> using namespace std;   // main() is where program execution begins. int main() {    cout << "Hello World"; // prints Hello World    return 0; } The C++ language defines several headers, which contain information that is either necessary or useful to your program. For this program, the header <iostream> is needed. The line using namespace std; tells the compiler to use the std namespace. Namespaces are a relatively recent addition to C++. The next line '// main() is where program execution begins.' is a single-line comment available in C++. Single-line comments begin with // and stop at the end of the line. The line int main() is the main function where program execution begins. The next line cout << "Hello World"; causes the message "Hello World" to be displayed on the screen. The next line return 0; terminates main( )function and causes it to return the value 0 to the calling process. Primitive Built-in Types C++ offers the programmer a rich assortment of built-in as well as user defined data types.
