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.

A Language is called as OOP  Language if a Language Provides us the Following Concepts Are Five Concepts in OOP’s:-

A C++ program can be developed from a basic structure. The general structure of C++ program with classes is as shown below (which is also called overview of a C++ program):

As we know that Software is a Program. And a Program is that which Contains set of instructions, and an Instruction contains Some Tokens. So Tokens are used for Writing the Programs the various Types of Tokens those are contained by the Programs.

Type Conversion is that which converts to data type into another for example converting a int into float converting a float into double The Type Conversion is that which automatically converts the one data type into another but remember we can store a large data type into the other for example we can't store a float into int because a float is greater than int.

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.

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 (<<).

Character set is the combination of English language (Alphabets and White spaces) and math's symbols (Digits and Special symbols). Character Set means that the characters and symbols that a C++ Program can understand and accept. These are grouped to form the commands, expressions, words, c-statements and other tokens for C++ Language.

A Program is a set of Instructions and a Programmer is that who develops the program .For creating a program a programmer must use a language called as the programming language So generally a programming language is used for creating the software’s.

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.

Constants refer to fixed values that the program may not alter. Constants can be of any of the basic data types. The way each constant is represented depends upon its type. Constants are also called literals.

Preprocessors are the Source of our Program those are Executed whey they are passing to Compiler and Preprocessors are always executed at the Time of Compilations. Preprocessors provide many features called Preprocessor directives and Each Preprocessor is declared with # symbol and This Directive must be written before a main program.

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.

Every word in C++ language is a keyword or an identifier. Keywords in C++ language cannot be used as a variable name. They are specifically used by the compiler for its own purpose and they serve as building blocks of a C++ program. C++ language has some reserve words which are called keywords of C++ language. These are the part of the C++ Tokens.

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.

The Memory is allocated in two ways either in Static and either in Dynamic. In Static Memory Allocation the Size of Memory may be Fixed and pre-defined but the Limitation of Static Memory is that when a user Stores Large Amount of data or Large Number of Elements are Increased instead the Declarable size of Numbers So The Concept of Dynamic Memory Allocation is used When we doesn’t know about the actual size or when we doesn’t known about the Number of elements For this purpose we uses Dynamic Memory Allocation.

We know that a computer can understand only Machine Language But the Program Written by a user is in the Form of English Language So it very necessary to convert the human Language into the Machine Language. So for this purpose we use Compiler which Converts human code into the machine code.

As we know that the Language which is used by a Algorithms is not Specific , means there is no Language which is used by a Algorithm .
