Used to execute statements a given number of times. Syntax for (int counter = 1; counter <= 10; counter++) { The first part is the initialization- it occurs before the loop starts. The second part is the condition that is checked before each iteration. The last is the update that executes after each loop iteration. Used to execute loop at least once and then check condition.
