One of the things computers are often used for is the automation of repetitive tasks. Repeating identical or similar tasks without making errors is something that computers do well and people do poorly.
We have seen programs that use recursion to perform repetition, such as
countdown. This type of repetition is called
iteration, and C++ provides several language features that make it
easier to write iterative programs.
The two features we are going to look at are the
while statement and
