Learning Outcomes
This book consists of 100 programing examples of Object Oriented
Programming C++. Starting from simple program and ending to graphics.
This book covers almost all the features of C++. The objective of this book
is to teach the students in an easy way. Students can not write a program in
the beginning. It will help the students to create programing skills in C++.
In the first step students try to run these programs and later on try to solve
it by their own method. However, there are several methods to solve a
problem. In these programs, a lot of code optimization space is available.
Now students may learn to optimize the code of these programs.

Introduction

C++ is the extension of C language. The C language was evolved
version of UNIX operating system [1]. C language is the subset of C++.
Every single command of C language is executable in C++ but the reverse
is not possible. C is a structured programing language but C++ is the
Object Oriented Programming language [2].
egan his
[3]. In 1983, it was renamed from C with Classes
to C++. New features were added along with classes.
In 1985, the first edition of the C++ programming language was
released [4]. In 1989, the second edition of the C++ was released [5]. In
1991, updated second edition of the C++ with new features was released.
C++ is standardized language by an ISO working group. In 1998,
after the second updated edition of C++ the ISO working group
standardized C++ for the first time which is known as C++98 [6]. In 2003,
it published a new version of the C++ standard called C++03 which fixed
problems identified in C++98 [7].
In 2011, the new version of C++11 standard was released with
adding numerous new features [8]. After a minor update in 2014, C++14
was released [9]. And various new additions are in pipe line for 2017.
As we know that computer understands only binary language that
consists of 0 and 1. It is also called machine language. And we write code
in high level language that is much closer to human language. Computer
does not understand human language. So we need a translator which
translates the code into machine language and then translate the results to
human language [10]. This translator some time works as compiler and
some time as interpreter.
Compiler translates the code as whole and show all the errors
existing in the code while interpreter translates the code line by line and if
any error is found in the code then it stops at that line. When program has
compiled successfully by compiler; it creates an object file with file

consists of a binary code and computer can
easily read this file. After compilation, program could run and it shows
output on the screen. Compiler translates and run the program as a whole so
it creates another file that is called executable fi
in the same folder. This file can be run directly. While interpreter translates
and execute code line by line so it does not create any object file nor an
executable file.
In C++ language, a compiler is used to translate the code. There are
many different types of compiler available to test the code. There are minor
differences between C++ compilers in its syntax. In this book, we are using
Follow the instructions given below step by step to execute the
in Microsoft Windows platform.
Download the programming language turbo C++ compatible for
the windows vista or windows 7/8/8.1/10 from the following link or other.
http://turboc7.blogspot.com/
Install the downloaded file into your computer.
Now you can run the Turbo C in full screen just double click on
desktop icon

By default graphics library is disable in turbo C. First of all enable it

O select Directorie
the directory setting is same as shown in the Fig. 1.2 below.

Follow the instructions given below step by step to compile and run
a program in turbo C++.
Progr type the code in the editor
or copy the text code of program and past it in notepad and save file with
file extension bin
Now open the file into the turbo C++ compiler and try to compile &
F keys.
When a program is compiled then the compiler create an object file
with same name. And when a program is run then the compiler generate
file extension in the same
directory. This file type is executed directly. But in Windows 7 or later
version of operating system these file could not execute directly because
operating system does not provide support.
So follow the instructions given below step by step to execute a program
Open the file menu in turbo C++

Now type the name of the exe file which you want to execute
directly.
