It is easy to learn the mechanics of a for loop or a ... wanted to use it in space, they’d be OK with that, too. The animations and commentary take you through algorithms ranging from the ...

This algorithm would allow five numbers to be inputted and would work out the total. A count-controlled loop would be used because it is known, in advance, how many times the algorithm needs to loop.

but it can be more difficult to find this function for more complicated algorithms. Use the following rules-of-thumb to simplify this task: These rules-of-thumb work best when a loop executes n ...

Yes/No’ say what the total is This algorithm would keep iterating until the answer at the end of the loop is ‘No’, ie it will continue to iterate WHILE there are more numbers to add.
