Why Use C++
C++ is one of the widely popular programming languages used in the world.
C++ is available in today's operating systems, Embedded systems and
graphical User Interfaces.
C++ is an object-oriented programming language which allows code to be
reused, and gives a clear structure to programs and lowering development
costs.
C++ is portable and can be used to develop applications that can be adapted
to multiple platforms.
C++ is handy and easy to learn!
As C++ is close to Java and C#, it is easy for programmers to switch to C++
or vice versa
1.2 C++ G S
ET TARTED
This step-by-step tutorial book teaches you the basics of C++.
Any prior programming experience is not required.
Two things are need before start using C++:
Many compilers and text editors to choose from are available. In this step-by-
step tutorial book, IDE will be used (see below).
C++ Install IDE
An “IDE (Integrated Development Environment)” is used to compile AND
edit the code.
Popular IDE's Code include: Eclipse, Visual Studio, and Blocks. All are free,
and they can be used to both debug and edit C++
co de.
Note: Web-
based also
can work, but with limited functionality.
Code:: Blocks is used in our step-by-step tutorial book, which is the correct
way to start.
You can find the latest version of Codeblocks
at http://www.codeblocks.org/downloads/26. Download the setup.exe of
mingw file, which installs the text editor with a compiler.
C++ Quickstart
We create our first C++ file as follows.
“Open Codeblocks and go to File > New > Empty File.
Write the following C++ code and save the file as myfirstprogram.cpp (File >
Save File as)”:
If you don't understand the code above, don't worry – the details will be
discussed in later chapters. For now, you focus should be on how to run the
code.
it should look like this In Codeblocks,:
Then, go to “Build > Build and Run” to execute (run) the program. The
below example shows the result:
Congratulations! Now you have written and executed your first C++
program.
1.3 C++ S
YNTAX
The following code breaks up to understand it better:
Example explained

Omitting Namespace
Some C++ programs can be executed without the need for standard
namespace library. The namespace std line is omitted and changed to
the std keyword, followed by the “::” operator for some objects:
1.4 C++ O (P T )
UTPUT RINT EXT
Together with the << operator, the “cout object” is used to print text/output
values:
Many “cout objects” can be added. However, note that a new line at the end
of the output cannot be inserted:
1.5 N L
EW INES
Inserting a new line can be done by using the \n character:
Note: a blank line can be created by two \n characters after each other:
A new line can also be inserted, with the “endl” manipulator:
