Introduction
1.1
About C++
1. C++ is a compiled, object oriented language.
2. It is the “successor ” to c, a procedural language.
• The “c++” is called the successor operator in C++.
• C++ was developed in the early 1980’s by Bjarne Stroustrup of
ATT Bell Labs.
3. C++ is a statically typed, compiled, case-sensitive , free-form programming language that support procedural, object oriented, and generic
programming(graphs, arrays).
1.2
Application Of C++
1. C++ is a versatile (flexible) language for handling very large programs.
It is suitable for virtually and programming task including development
of editors, compilers, database, communication systems and any complex real-life application systems.
2. Since C++ allows us to create hierarchy-related object, we can build
special object-oriented libraries which can be used later by many programmers.

Data Types & Operators
2.1
Data Types & Their Description
1.Basic Data Types
They are arithmetic types and are further classified into:
• Integer Type
• Floating type
2. Enumerated types
They are again arithmetic types and they are used to define variables that
can only assign certain discrete integer values throughout the program.
3. The Type Void
The type specifier void indicates that no value is available.
4. Derived Types
They include
• Pointer types
• Array types
• Structure types
• Union types
• Function types

Flow Of Control
3.1
C++ Loop Types
There may be a situation, when you need to execute a block of code several
number of times. In general, statements are executed sequentially: The first
statement in a function is executed first, followed by the second, and so on.
A loop statement allows us to execute a statement or group of statements
multiple times and following is the general from of a loop statement in most
of the programming languages

Functions
4.1
C++ Functions
A function is a group of statements that together perform a task. Every
C++ program has at least one function, which is main(), and all the most
trivial programs can define additional functions.
You can divide up your code into separate functions. How you divide up
your code among different functions is up to you, but logically the division
usually is such that each function performs a specific task.
A function declaration tells the compiler about a function’s name, return
type, and parameters. A function definition provides the actual body of the
function.
The general form of a C++ function definition is as follows
10
Downloaded by Yash Mittal (ymittal5277@gmail.com)
lOMoARcPSD|16501318
A C++ function definition consists of a function header and a function
body. Here are all the parts of a function
• Return Type : A function may return a value. The returnType is the
data type of the value the function returns. Some functions perform
the desired operations without returning a value. In this case, the
returnType is the keyword void.
• Function Name : This is the actual name of the function. The function
name and the parameter list together constitute the function signature.
• Parameters : A parameter is like a placeholder. When a function is
invoked, you pass a value to the parameter. This value is referred to as
actual parameter or argument. The parameter list refers to the type,
order, and number of the parameters of a function. Parameters are
optional; that is, a function may contain no parameters.
• Function Body : The function body contains a collection of statements
that define what the function does.

Classes and Objects
5.1
C++ Classes
The main purpose of C++ programming is to add object orientation to
the C programming language and classes are the central feature of C++
that supports object-oriented programming and are often called user-defined
types.
A class is used to specify the form of an object and it combines data representation and methods for manipulating that data into one neat package.
The data and functions within a class are called members of the class.
C++ Class Definitions
When you define a class, you define a blueprint for a data type. This doesn’t
actually define any data, but it does define what the class name means, that
is, what an object of the class will consist of and what operations can be
performed on such an object.
A class definition starts with the keyword class followed by the class
name; and the class body, enclosed by a pair of curly braces. A class
definition must be followed either by a semicolon or a list of declarations.

For example, we defined the Box data type using the keyword class as
follows
The keyword public determines the access attributes of the members of
the class that follows it. A public member can be accessed from outside the
class anywhere within the scope of the class object. You can also specify
the members of a class as private or protected which we will discuss in a
sub-section.
Define C++ Objects
A class provides the blueprints for objects, so basically an object is created
from a class. We declare objects of a class with exactly the same sort of
declaration that we declare variables of basic types. Following statements
declare two objects of class Box
Both of the objects Box1 and Box2 will have their own copy of data
members.
