Introduction to These Tutorials:

Welcome to c++ tutorial step by step. You can learn easily in this tutorial. If you are a beginner or advanced level yet you will learn it. C programming was developed  in 1979 by Bjarne at the Bell Telephone Laboratories for the UNIX os system. Its programming language favorite  for every software engineer.


Why to Learn C++ Programming with advantage? In this program make a great programmer. It can’t suffer from learning and the code editor IDE is very simple. Now bargain advantage learning of c++ programming. 

  • It is a low level programming language so it is used for hardwire. On the other hand, unbelievable  memory management is very high performance.
  • It is an Object Oriented programming language. So, we can get an OOP concept that is very interesting.
  • It’s user friendly functions and library. C programming is a green programming language because it can solve big problems that can be seen online.
  • Easy to understand and lightweight program make.
  • This programming is very portable and it runs multiple operating systems like Linus, Windows and MAC using the same Code .
  • Full control pointer.
  • Using this programming language makes system software and application software. 

What are the disadvantages of C++ and describe? Cpp has a lot of problems, one of them being several security issues. You will need another way. Now bargain disadvantage learning of c++ programming.

  • A lot of memory space is needed compared to other programs.
  • Basic OOP concept is at a very core level.
  • It is a case sensitive language so it faces many problems.
  • C ++ is an insecure programming language. Pointers, global variables, etc. are insecure so any hacker can hack the program.
  • It is very difficult to syntax so the programmer forgets to write the correct syntax.
  • C++ have lack of algebraic data types.
C++ Overview

Hello world code run using c++ programming. First you need a Code editor and IDE. I’m using Code Block if you are interested in downloading and using the software.

Installing an Integrated Development Environment (IDE):

I recommend every programmer to use CodeBlock. Because, It has Integrated all are things like code editor, IDE etc. Download and install without problem. Codeblock has more features like cross platform install windows, mac, Linux. CPP and c program integrate both IDE and get two things. This is user friendly and the UI/UX very beautiful. If you face any problem, search YouTube and find the problem. This application uses IDE GCC included. It’s license is  GPL-3.0-only. On the other hand, codebook is open source software.

#include <iostream>

using namespace std;

// main() threre is main section of the programm

int main() {

   cout << “Hello World”; // like printf function

   return 0; // programm off section


What are some frequently asked C++ questions in interviews?

First question, What is object-oriented-programming language? Answers is Object oriented programming is a concept which contains data and code.It’s main feature can often modify its own data fields. 

Second question, What are the basic components of the OOP language? Object oriented has four concepts for example, encapsulation, abstraction, inheritance, and polymorphism. VIVA board you can ask What is encapsulation, abstraction, inheritance, and polymorphism in OOP? You will answer, step by step.

Encapsulation: Encapsulation is the process that protects the object from being denied access outside the data functions. 

Abstraction: This is a data type description technique where data is contained and functions are accessed.

Inheritance: The ability to take data from a function and store data in a new function is called inheritance.

Polymorphism: The function of the same object in different states taking many forms and giving different results is called polymorphism.

How is C++ different from Python?

You are given an answer given with confidence. CPP is using general purpose and Python is using a high level programming language. CPP is hard for Python and python code is easy to write. CPP can’t make web applications and Python using it can make web applications. 

What is the difference between Recursion and Iteration ? Iteration means working on loop and recursion is a method of solving a computational problem. Iteration is time complexity very low and recursion requires more time. Recursion and Iteration are functions, for loop. Recursion large size and Iteration small size.

Compiler, linker, and libraries function: 

Compiler is like a translator. It converts high level language  to low level language. Every programming language is made by an individual compiler. Low level code is called machine programming code. Compiler compiles the program all code together. Who are working line by line which is called an interpreter. Compiler and interpreter both have the same task but working procedure difference. Linker programs some to the same program compiler and interpreter. Machine program for running needs a function that is linked and it links to other functions. A function that cannot be created before it is created is called a library function for example, std::cout << and return etc.
