History of C++

1. C++ programming is an essential of C programming language
2. In 1971 Dennis Ritchie at Bell labs invented C programming language after reforming and rewriting the compiler of B language. So C is a modified version of B language.
3. In 1983 C++ was invented at Bell labs by Bjarne Stroustrup.
4. C++ is an advanced, powerful language, and easy to learn.
5. C++ is a compiled programming language, This means original source code is translated into machine language, before run.
6. C++ is a third generation programming language.

Compiler:

A compiler is a very specialized computer program that translates Source Code into Machine Code. 

Important point regarding C++ asked in viva exams:

• The #include statement is used to insert the header code so your program may use the functions defined in the header file.
• C++ supports inline functions, and constants, so is consequently more often used just for header file inclusion and conditional compilation statements.

• Pre-processor directives are preceded with a #. The # should always be placed in the first column of the line

  Angled brackets are used to instruct the pre-processor to find the header files from the standard header file directory

                                              #include <iostream.h>

Comments in C++

Block Comments:  /*Write your more than one line Comment Between these symbols */

In-Line Comments: //one line comment goes here

Inline comments may be nested within block comments, or even inline comments.

/*

Start of a block comment.

// A legal inline nested // comment End of a block comment.

*/
