What is C++? Everything You Need To Know [Beginners Guide]
C++ language is one of the top 10 programming languages in the world. According to StackOverflow survey and TIOBE Index, C++ language is the most popular programming language in the world. The popularity of C++ language is due to some of its amazing features.
Let’s understand in detail about what is C++ language?, what is the history of C++?, what are the features of C++?, and why should you learn C++ language?
What is C++
C++ language is a general purpose, object-oriented programming language created by Bjarne Stroustrup in 1979.
C++ language is similar to C language. We can make all the programs made in C language very easily in C ++ language without any changes or with minor changes.
We can say that C ++ language is a superset of C language, which has the features of C language as well as some other additional features as well.
C++ is an efficient and powerful programming language which is mainly used in GUI platforms and 3D graphics.
C++ language has much bigger function libraries than C language which makes it much more simple and convenient than C language.
C ++ language is also a middle-level programming language like C language, in which we can create both low level and high-level programs very easily.
Due to this feature of C++ language, both application software and system software are made with its help.
History of C++
Bjarne Stroustrup started working on the C++ language in 1978 and released its first version in 1979. Initially, according to them, this was not a new programming language, they said that it was an extended version of the C language.
When Bjarne Stroustrup added the concept of Classes to the C++ language, it was called “C With Classes” at that time.
Bjarne Stroustrup added some more new concepts along with Classes, due to which the language created by Bjarne Stroustrup in 1983 was named C++.
The increment operator “++” in C++ indicates that the C++ language is an extended version of the C language.
The C++ language was standardized by the ISO committee in 1998 and a minor update was released in 2003, due to which it was called C++03.
In 2011, 2014, and 2017 new standards of C++ language were released, due to which C++ language was called C++11, C++14, and C++17.
Every new standard of C++ language comes with a new feature that helps the programmer a lot in programming.
Features of C++ Language
The C++ language has the following characteristics:
- Statically typed
- Compiler Based
- General-Purpose Language
- Case Sensitive
- Object-Oriented Programming
1. Statically typed
C++ language is a statically typed programming language in which the data type of the variable is checked at compile-time instead of at run time.
2. Compiler Based
C ++ language is a compiler-based programming language in which programs cannot be executed or run without compilation.
The program made in C ++ language is first converted into machine language with the help of compiler, then we can execute that program.
3. General Purpose Language
C ++ language is a general purpose programming language, in which we can create almost all types of software from application software to system software.
4. Case Sensitive
C++ is a case sensitive programming language in which words written in lower case letters and upper case letters have different meanings.
5. Object-oriented Programming
C++ is an object-oriented programming language in which programs are made by treating things as an object.
Why Learn C++
If you want to become a good software engineer then you must learn C++ language.
There are many other advantages of C++ language which I have mentioned below.
- C ++ language is very close to the hardware, with the help of this we can do low-level programming. We can do memory management very easily through a program made with the help of C ++ language.
- With the help of C++ language, you can learn object-oriented concepts very easily. Object-oriented concept makes your further programming journey easy.
- If you learn C++ language then it will be very helpful in your campus requirement process. If you become a good C++ software developer then companies pay you more.
- Through using C++, you are able to create both system software and application software.
There are thousands of such benefits of learning C ++ language, but if you want to become a good software engineer and have made a career in the IT field, then you must learn it.
Hello World using C++ Language
I am showing you a traditional Hello world program with the help of C++ language so that you can have some idea how to write code in C++ language.
#include <iostream>
using namespace std;
// main() is a function from where the execution of the program starts.
int main()
{
cout << "Hello World"; // prints Hello World
cout << "Welcome to CsTutorialpoint";
return 0;
}Output
Hello World
Welcome to CsTutorialpointRight now you don’t think much that what is the meaning of the code written in it, when you start learning C ++ language, then everything will be clear to you gradually.
