C++ Basic Syntax

In the previous post, you learned to create simple Hello World program in C++ by using Notepad or Dev-C++ editor. This tutorial teaches you the basic syntax of C++ programming language that you should know since you are new to this computer programming language.


- #include<iostream>
It is a statement written down to include iostream header file that will allow us to use the command to receive input from users and display text on the screen.


- using namespace std;
The statement will import std namespace and allow us to use commands without having to type out their full names.
A namespace defines names of variables or functions so that they do not conflict with other variables or functions that have the same names.


- C++ program will start from the main method:
int main()
{


}


-return 0;
This statement will tell the C++ compiler that your program ends here without any error.
A value other than zero will be treated as abnormal termination by the operationg system.


-cout followed by <<

 It is used to print text on the screen.
