Flowcharts are necessary for any program longer than 50 lines (and sometimes even for those).<br><br>Be lucky you don't have to tackle static and dynamic diagrams yet. Or swimlanes.

Iteration When designing algorithms, there may be some steps that need repeating. This is known as iteration, and can be displayed in pseudocode or flowcharts.

Representing sequencing in pseudocode Writing in pseudocode is rather like writing in a programming language . Each step of the algorithm is written on a line of its own, in sequence.
