Using count-controlled iteration can lead to fewer programming errors and more flexible programs. As can be seen above, using iteration makes a program simpler, less error-prone and more flexible.

Blocks are fundamental to structured programming, where control structures are formed from blocks." Iteration works similarly in a list- the program goes left-to-right, starting with the first element ...

With a while loop, the code within the iteration may never be executed. With a repeat loop, the code is always executed at least once. The condition for a do construct is placed at the end of the ...
