If you are familiar with printf in C language it is similar to cout. The only difference is there is no need of format specifiers while using cout.
It is always used with extraction operator (<<). To use cout<< you need to include <iostream> in your code.
Basically you know that the CPP is a object oriented programming language ,so the cout is a object of the iostream class
the main difference between the printf and the cout is that ,printf is a predefined function and cout is a object
Cout is object of class iostream
It is use to get output print on console screen
If you are familiar with C language Printf it does same thing of printing only difference is cout doesn't require any Format specifier to print
Cout is use to print character or alphabet on screen..
It doesn't require any format specifier.
To cout or cin you need class call iostream.h
You can also say Cout is obj of class iostream
And one last thing
Cout means console output
