Unit 3: Object-Oriented Programming in C++

3.3.7 The Manipulators endl and setw

A manipulator is a command in C++ that is used for formatted output.

endl Manipulator:

The endl manipulator causes a linefeed in the cout statement so that the subsequent text is displayed on the next line.

setw Manipulator:

• It is used in the output statement to set the minimum field width.
• The number of columns used to display a value on the screen is called field width.
• It has the general form:

                                        setw(n)

• n is an integer value which defines a number of columns within which a number or text is to be printed.
