6.2. Iteration

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 nLines and 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 the for statement.
