C++ Introduction And Tutorial For Beginners

Friends C ++  is an (OOPL) so before you start reading of c++ Introduction and tutorial for beginners it would be good to know what is the object-oriented programming language and why it is used once.

  • Tutorial  Of Introduction c++


C ++ is an object-oriented programming language. C ++ was developed by Bjarne Stroustrup. Before the ++ Introduction and tutorial for beginners and Simula 67 were two popular languages. Bjarne Stroustrup wanted to create such a language together with both languages, which has all the features of object-oriented programming. The result of their thinking was C ++.

  • c++  Features


C ++ was developed in Bell laboratories in 1979. C ++ is a middle-level language. It has features of high level and low-level languages. All features of C language are found in C ++.

There Are 3 Important Features Of C ++.

Object-oriented
Low level
Easy to learn


C ++ is used and how you can use it, let's try to get it.

C ++ is mostly used in software where more control is required on the hardware. Like C ++ is used to create device drivers.

C ++ is a multipurpose language. It can be used to create large software for you.

Today C ++ is used mostly for the purpose of education. Because the features of all major languages have been taken from C ++. If you understand C ++ then you can easily understand other languages as well.

The extension of C ++ c language is. Therefore, all those software that can be created can also be made in C ++.

If you want your software to work at the lower level as well as you can use C ++ at the higher level.
Mostly, any new programming language does not openly support the pointer. If you want to create a software using pointers, you can use C ++.

  • C++ Object-oriented Principles


Class - Class is a user-defined data type. This is similar to the structure in C language. But in classes, you can create variables along with them related functions which can be accessed later by objects. Provides a data-centered approach to a class programmer. By class, you can separate the variables and related functions.

Objects - As you know, a class is a user-defined data type. Classes of variables are called objects. By Object, you can access the class's variables and functions.

Abstraction - Abstraction means that the end user should be shown the same functionality which he needs to hide the remaining background function. For example, when you drive a car, you focus only on clutch, gear, and steering, you do not have any sense about how the engine is working.

Encapsulation - Encapsulation is also called data hiding. Encapsulation is an object-oriented programming feature that binds data members (variables) and related functions such as a class. Data and functions are protected from outside access, as well as encapsulation. Encapsulation properties provide the protection of 3 level (Public, Private, Protected). C ++ is implemented through encapsulation classes.


Inheritance - Inheritance is the concept of object-oriented programming, in which a code can be used elsewhere. This principle code re-usability is implemented. For example, you can inherit the functions created in a class in second class, by doing so, you will not need to re-write these functions and you will be able to access them from the objects of both classes.

Polymorphism - Polymorphism means a name that has many things. In it, you implement many types of tasks by one name. The polymorphism function in C ++ is implemented by overloading in which the functions of a name are executed in different conditions.

Message passing - Objects in object-oriented programming interact with each other, from which the program represents real life condition.

  • Sample Program And Example Of C++  

#include<iostream.h>
int main() {
return 0;
cout<<"yes i am";
}


This example is being explained below.

The header file is included in the first line. You need this header file to show the output on the screen.

After this, the main method of the program has been started.

Simple message has been printed by count function.

The function has been returned by the return statement.

The above program produces the below-given output.

 yes i am  

In this tutorial, you have learned about C ++ history, applications, and different features. Data in any program is important. All operations are performed only on data. Before you start programming in C ++, you need to know about the various data types of C ++
