C++ cout - Basic Output Operation in C++

In this article, we will be focusing on C++ cout statement to perform the output operation in C++. In C++, cout is an object of ostream class. It accordingly displays the output values on the console/screen. The cout object holds its cords with the standard C output stream stdout. When we give a call to the cout object, it invokes the action of class ostream i.e. output stream and streams the data into a pipeline of bytes.

In this article, we will be focusing on C++ cout statement to perform the output operation in C++.

So, let us begin!!

Working of C++ cout

In C++, cout is an object of ostream class. It accordingly displays the output values on the console/screen. The cout object holds its cords with the standard C output stream stdout.

When we give a call to the cout object, it invokes the action of class ostream i.e. output stream and streams the data into a pipeline of bytes.

In c++, we fetch or display the data in the form of sequence of bytes known as Stream. Through output stream, the data is pulled from the main memory using the cout object and displayed on the screen.

Let us now focus on the structure of cout object in the upcoming section.

Syntax of cout in C++

Have a look at the below syntax!

#include<iostream>

cout<<``"text"``;

OR

cout<<variable;

For the cout object to get called, it is necessary to import the iostream header file. The iostream class contains all the necessary functions to perform and invoke the objects such as cout, cin, etc.

Further, we use insertion operator(<<) along with the cout statement to display the values on the screen.

Having understood the syntax, let us now implement the concept through the below examples.
