C++ is a statically typed, compiled, general-purpose, case-sensitive, free-form
programming language that supports procedural, object-oriented, and generic
programming.
C++ is regarded as a middle-level language, as it comprises a combination of both high-level and low-level language features.
C++ was developed by Bjarne Stroustrup starting in 1979 at Bell Labs in Murray Hill, New Jersey, as an enhancement to the C language and originally named C with Classes but later it was renamed C++ in 1983.
C++ is a superset of C, and that virtually any legal C program is a legal C++ program.
Note: A programming language is said to use static typing when type checking is performed during compile-time as opposed to run-time. Object-Oriented Programming C++ fully supports object-oriented programming, including the four pillars of object-oriented development: Encapsulation Data hiding Inheritance Polymorphism Standard Libraries Standard C++ consists of three important parts: The core language giving all the building blocks including variables, data types and literals, etc. The C++ Standard Library giving a rich set of functions manipulating files, strings, etc. The Standard Template Library (STL) giving a rich set of methods manipulating data structures, etc. The ANSI Standard The ANSI standard is an attempt to ensure that C++ is portable; that code you write for Microsoft's compiler will compile without errors, using a compiler on a Mac, UNIX, a Windows box, or an Alpha. 1. OVERVIEW C++ 2 The ANSI standard has been stable for a while, and all the major C++ compiler manufacturers support the ANSI standard. Learning C++ The most important thing while learning C++ is to focus on concepts. The purpose of learning a programming language is to become a better programmer; that is, to become more effective at designing and implementing new systems and at maintaining old ones. C++ supports a variety of programming styles. You can write in the style of Fortran, C, Smalltalk, etc., in any language. Each style can achieve its aims effectively while maintaining runtime and space efficiency. Use of C++ C++ is used by hundreds of thousands of programmers in essentially every application domain. C++ is being highly used to write device drivers and other software that rely on direct manipulation of hardware under real-time constraints. C++ is widely used for teaching and research because it is clean enough for successful teaching of basic concepts. Anyone who has used either an Apple Macintosh or a PC running Windows has indirectly used C++ because the primary user interfaces of these systems are written in C++. C++ 3 Try it Option Online You really do not need to set up your own environment to start learning C++ programming language. Reason is very simple, we have already set up C++ Programming environment online, so that you can compile and execute all the available examples online at the same time when you are doing your theory work. This gives you confidence in what you are reading and to check the result with different options. Feel free to modify any example and execute it online. Try the following example using our online compiler option available at http://www.compileonline.com/ #include
using namespace std;
int main()
{
cout << "Hello World";
return 0;
}
For most of the examples given in this tutorial, you will find Try it option in our
website code sections at the top right corner that will take you to the online
compiler. So just make use of it and enjoy your learning.
Local Environment Setup
If you are still willing to set up your environment for C++, you need to have the
following two softwares on your computer.
Text Editor:
This will be used to type your program. Examples of few editors include Windows
Notepad, OS Edit command, Brief, Epsilon, EMACS, and vim or vi.
Name and version of text editor can vary on different operating systems. For
example, Notepad will be used on Windows and vim or vi can be used on
windows as well as Linux, or UNIX.
The files you create with your editor are called source files and for C++ they
typically are named with the extension .cpp, .cp, or .c.
A text editor should be in place to start your C++ programming.
