C++ Tutorial

C++ Tutorial

C++ is a middle-level programming language developed by Bjarne Stroustrup starting in 1979 at Bell Labs. C++ runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This C++ tutorial adopts a simple and practical approach to describe the concepts of C++ for beginners to advanded software engineers.

Why to Learn C++

C++ is a MUST for students and working professionals to become a great Software Engineer. I will list down some of the key advantages of learning C++:

  • C++ is very close to hardware, so you get a chance to work at a low level which gives you lot of control in terms of memory management, better performance and finally a robust software development.

  • C++ programming gives you a clear understanding about Object Oriented Programming. You will understand low level implementation of polymorphism when you will implement virtual tables and virtual table pointers, or dynamic type identification.

  • C++ is one of the every green programming languages and loved by millions of software developers. If you are a great C++ programmer then you will never sit without work and more importantly you will get highly paid for your work.

  • C++ is the most widely used programming languages in application and system programming. So you can choose your area of interest of software development.

  • C++ really teaches you the difference between compiler, linker and loader, different data types, storage classes, variable types their scopes etc.

There are 1000s of good reasons to learn C++ Programming. But one thing for sure, to learn any programming language, not only C++, you just need to code, and code and finally code until you become expert.

Hello World using C++

Just to give you a little excitement about C++ programming, I'm going to give you a small conventional C++ Hello World program, You can try it using Demo link

C++ is a super set of C programming with additional implementation of object-oriented concepts.

#include <iostream>
using namespace std;

// main() is where program execution begins.
int main() {
   cout << "Hello World"; // prints Hello World
   return 0;
}

There are many C++ compilers available which you can use to compile and run above mentioned program:

  • Apple C++. Xcode

  • Bloodshed Dev-C++

  • Clang C++

  • Cygwin (GNU C++)

  • Mentor Graphics

  • MINGW - "Minimalist GNU for Windows"

  • GNU CC source

  • IBM C++

  • Intel C++

  • Microsoft Visual C++

  • Oracle C++

  • HP C++

It is really impossible to give a complete list of all the available compilers. The C++ world is just too large and too much new is happening.

Applications of C++ Programming

As mentioned before, C++ is one of the most widely used programming languages. It has it's presence in almost every area of software development. I'm going to list few of them here:

  • Application Software Development - C++ programming has been used in developing almost all the major Operating Systems like Windows, Mac OSX and Linux. Apart from the operating systems, the core part of many browsers like Mozilla Firefox and Chrome have been written using C++. C++ also has been used in developing the most popular database system called MySQL.

  • Programming Languages Development - C++ has been used extensively in developing new programming languages like C#, Java, JavaScript, Perl, UNIX’s C Shell, PHP and Python, and Verilog etc.

  • Computation Programming - C++ is the best friends of scientists because of fast speed and computational efficiencies.

  • Games Development - C++ is extremely fast which allows programmers to do procedural programming for CPU intensive functions and provides greater control over hardware, because of which it has been widely used in development of gaming engines.

  • Embedded System - C++ is being heavily used in developing Medical and Engineering Applications like softwares for MRI machines, high-end CAD/CAM systems etc.

This list goes on, there are various areas where software developers are happily using C++ to provide great softwares. I highly recommend you to learn C++ and contribute great softwares to the community.

Audience

This C++ tutorial has been prepared for the beginners to help them understand the basic to advanced concepts related to C++.

Prerequisites

Before you start practicing with various types of examples given in this C++ tutorial,we are making an assumption that you are already aware of the basics of computer program and computer programming language.

Frequently Asked Questions about C

There are some very Frequently Asked Questions(FAQ) about C, this section tries to answer them briefly.

In the early 1970s, an American computer scientist named Dennis M. Ritchie developed the C programming language at Bell Laboratories.

The latest version of C language is C17 which is going to be replaced by C23 in 2024.

C programming language has several features which are as follows −

  • Procedural programming language
  • Modular
  • It has a rich set of built-in operators.
  • Fast and efficient.
  • Portable

Frequently Asked Questions about C++

There are some very Frequently Asked Questions(FAQ) about C++, this section tries to answer them briefly.

C++ is used for developing system software, games, embedded systems, scientific computing, IoT devices and many more.

There are 6 versions of C++ language namely C++98, C++03, C++11, C++14, C++17, and C++20.

C++ programming language has several features which are as follows −

  • Object Oriented Programming language.
  • Allow dynamic memory allocation.
  • It has a rich set of libraries.
  • It is adaptable to a wide variety of applications.
  • Portable

A typical C++ program consists of preprocessors, global and local declarations, main() function, loops, expressions, and user-defined functions.

You can use our simple and the best C++ tutorial to learn C++ programming language. We have removed all the unnecessary complexity while teaching you C++ concepts.

C++ developers are responsible for planning, designing, and developing apps and software using C++ programming language. After the development, their tasks also include the maintenance of these software.

There are only two standard libraries in C++ language namely old C library (libc.lib) and new C++ library (libcp.lib).

Following are the skills of a C++ developer −

  • Must be proficient in C++ language.
  • Have a good knowledge of object-oriented programming language.
  • Good problem solver.
  • Knows how to manage the memory utilization.
  • Must be familiar with the version control system.

Here is the summarized list of tips which you can follow to learn C++ −

  • First and most important to make up your mind to learn C++.
  • Install the required IDE and other software that are essential for C++ on your computer system.
  • Follow our tutorial step by step starting from the very beginning.
  • Read more articles, watch online courses or buy a book on C++ to enhance your knowledge.
  • Try to develop small software or projects using C++.

You can learn the basics of C++ language in as little as two to three weeks. However, it may take months of practice to fully master it. Determining how long it takes to learn C++ also depends on how you plan to use it.
