Before designing an algorithm it is important to first understand what the problem is. Algorithms can be designed using pseudocode or a flowchart, and the standard notations of each should be known.

Any algorithms designed using pseudocode will not run unless they are converted into an actual programming language. This simple pseudocode algorithm asks a user to input their favourite subject: ...

We implemented an error-checking algorithm in a World Wide Web-based program that can be used through the Internet even by computer nonspecialists.
