Unit 3: Object-Oriented Programming in C++

3.3.1 The cout Statement

It is used to display text or values on the 

                    cout<<“character string”/variable;

• “<<“ is called the insertion operator which displays the contents of the character string or the value stored in a variable on the screen.
• The insertion operator may be used more than once in a single statement.

Example

#include <iostream.h>
#include <conio.h>
void main()
{
            crlscr();
