2 Some of the methods of algorithm description used today are:

flowcharts, pseudocode, structured English, Nassi-Schneiderman diagrams and English prose. The two methods approved for this course are flowcharts and pseudocode. The graphical method is the flowchart. The method that uses English-like language is called pseudocode. When using flowcharts, we read them from top to bottom and left to right, moving from step to step along flowlines. Pseudocode is popular because its keywords are close to those in programming languages.
