C++ Programming Tutorial for Beginners | Free Online Professionals Guide for C++ with Examples

In the previous article, we have discussed about C++11 Tutorial for Beginners & Professionals. Let us learn About Programming Tutorial for Beginners in C++ Program.

Beginners who want to learn and get a good grip on the C++ Programming Language can refer to this free BTech Geeks online CPP tutorial. Firstly, you should have some knowledge about CPP Language like core and basics of it. The most powerful and flexible general-purpose programming language is C++ which is also known as a middle-level programming language developed by Bjarne Stroustrup commencing at Bell Labs in 1979.

It supports running on a variety of platforms like Windows, Mac OS, and the different versions of UNIX. Furthermore, it also promotes various ways of programming such as object-oriented, procedural, functional, and many more. Our Free & Ultimate Tutorial of C++ Programming guide helps in understanding the different concepts of CPP from beginners to advanced coding professionals within no time.

What is C++ Programming Language?

C++ is an object-oriented programming language, an extension to C programming. C++ programming is a multi-paradigm language that supports a minimum of seven varieties of programming styles.

It is used for developing games, operating systems, desktop apps, and many more as it is a general-purpose language. Due to the comprehension of rich function libraries, developing the required logic in C++ can be simpler and handy compared to the C language.

Prerequisites for Learning C++ Language

This C++ for beginners tutorial will make you learn and understand various types of C++ Concepts with examples. But, beginners or professionals should have some idea on basics of computer program and its languages for better learnings of this object-oriented programming language ie., C++.

Standard Libraries of C++

The C++ programming standard libraries are broken into three essential parts:

  • Data types, variables, and literals, etc are covered in the core library.
  • The standard library holds the set of functions managing strings, files, etc.
  • The Standard Template Library (STL) comprises the set of methods handling a data structure.

Why Learn C++?

  • Learning C++ language is the best way to code independent programs in various advanced programming languages like Java, Python, etc.
  • It is much similar to hardware, thus you grab an opportunity to perform at a low level which provides you a lot of control relating to memory management, robust software development, and better performance.
  • Million of software engineers used this programming language in developing application and system programming.
  • One of the best things, you can observe in C++, it indeed teaches you the difference between compiler, linker, and loader, different data types, storage classes, variable types their scopes, etc.
  • C++ supports grasping the internal architecture of a computer, how the computer stores and retrieves data.

Applications of C++ Programming Language

As I said prior, C++ is the most popularly used programming language by software candidates. The presence of C++ is almost in every area of software development so we have listed a few of them below. Have a glance at them before you start learning the C++ language perfectly:

  • Application Software Development
  • Programming Languages Development
  • Games Development
  • Computation Programming
  • Embedded System

Features of C++

In this C++ Programming Tutorial, you even observe various features of the language that helps significantly while programming any of the application in C++. They are as fashion

  1. Object-Oriented: C++ is an object-oriented programming language that supports all its advanced features like Abstraction, Inheritance, Encapsulation, and Inheritance in C++ programs. Also, it makes you feel easier while coding.
  2. Structured Programming Language: C++ functions support coders to divide the problem into small blocks of the program and structured like a program enhances readability and reusability.
  3. Robust & Protable: Programming in C++ is simply easy. Mostly, the compilers of C++ are supported by ANSI Standards which makes them portable. Also, it is not a fully platform-independent language thus leads some of the things in C++ to be not portable like designing graphics-oriented applications as it has no GUI API or graphics.
  4. Better Memory Management: You can dynamically allot memory while runtime with the help of operators like new and delete in C++ to have superior memory management.
  5. Exception Handling: There is no support to perform exception handling in C++ like the Java programming language. As makes it easier to identify and handle the exceptions.

C++ Programming Example

The represented instance is a small conventional C++ Hello World program that gives you the output text as Hello World.

#include <iostream>
using namespace std;

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

C++ Compilers

Providing the complete list of available compilers in c++ is impossible as you can see the work of CPP is too huge. So, we have enlisted some of the available CPP compilers that can be used to compile and run the above-illustrated program:

  • Apple C++. Xcode
  • Oracle C++
  • Bloodshed Dev-C++
  • IBM C++
  • GNU CC source
  • Clang C++
  • Intel C++
  • Cygwin (GNU C++)
  • Microsoft Visual C++
  • Mentor Graphics
  • HP C++
  • MINGW – “Minimalist GNU for Windows”
