C++ User Input

This lesson is part of C++ · All levels

Summary

This lesson teaches you how to make a program receive data from a user via a keyboard. The ring object of the iostream header is used along with the operator >> to read values into the variable. So the program is no longer static and can respond to user input.

Key points

The cin is used to read input from the standard input (keyboard).
The operator >> directs the data from the input to the variable.
The variable must be declared before receiving a value from the ring.
Some inputs can be read in sequence in a single sentence.
