Join Barron Stone for an in-depth discussion in this video For loops, part of Programming Foundations: Real-World Examples.
- Loops are programming constructs…which repeatedly perform an operation…or series of operations over and over and over.…There are two types of loops, for loops and while loops.…One of the key differences between them…is that with a for loop, you know exactly how many times…that loop is going to perform its operation…before it even runs.…Some languages do this by creating a variable…that will count up to a certain value…and for loops can also be used to…iterate through items in a list.…That list will have a certain number of items…which will be the number of times the for loop executes.…
With a while loop, you don't know how many times…a loop is going to be executed.…Instead, as the loop is running,…it's constantly checking and checking…for a condition to determine whether or not…it should execute one more time.…I'll use loops to help me perform a complex operation…that I'm very familiar with, doing the dishes.…My kitchen is a little bit of a mess…and I want to clean it up before my friends come over.…I'll start by loading the dirty dishes from the sink…
