Escape Sequences

Commonly used escape sequences are \n, \t and \a. The escape sequences are enclosed in single quotes. \n is a new line character and helps in transferring control to the next line. If more than one line is to be skipped, \n is repeated as many times as the number of lines to be skipped. \n can also be combined with any other message string to be displayed. \t is used for giving tab and \a is used for giving a beep.

cin and cout are two predefined objects which represent standard input and output stream. The standard output stream represents the screen, while the standard input stream represents the keyboard. These objects are members of iostream class. Hence the header file <iostream.h> should be included in the beginning of all programs.

C++ supports comment format which is indicated by a II sign before the comment. In this case, the comment can proceed only till the end of current line. In case it is required to extend the comment beyond the current line, the comments should be preceded by the II symbol on subsequent lines also.

A combination of variables, constants and operators that represents a computation forms an expression. Depending upon the type of operands involved in an expression or the result obtained after evaluating expression, there are different categories of an expression. These categories of an expression are discussed here.

A data type determines the type and the operations that can be performed on the data. C++ provides various data types and each data type is represented differently within the computer's memory. The various data types provided by C++ are built-in data types, derived data types and user-defined data types as shown in Figure.

In C++, input and output (I/O) operators are used to take input and display output. The operator used for taking the input is known as the extraction or get from operator (>>), while the operator used for displaying the output is known as the insertion or put to operator (<<).

Programs are a sequence of instructions or statements. These statements form the structure of a C++ program. C++ program structure is divided into various sections, namely, headers, class definition, member functions definitions and main function.

To develop software, the object-oriented concepts need to be implemented in any high-level language. The high-level language that implements the concepts of object-oriented programming is known as an object-oriented language (also called an OO language). In general, an object-oriented language must support all or some of these OO concepts.
