Often we use a for or while loop to go through a list of items or the contents of a file and we are looking for something such as the largest or smallest value of the data we scan through.

These loops are generally constructed by:

Initializing one or more variables before the loop starts
Performing some computation on each item in the loop body, possibly changing the variables in the body of the loop
Looking at the resulting variables when the loop completes

We will use a list of numbers to demonstrate the concepts and construction of these loop patterns.
