Students should be able to:

  1. Explain the concepts of algorithms and flowcharts

Content

 

Algorithm is the step-by-step procedure of solving a particular problem. It is simply a sequence of clear and precise instructions for solving a particular problem. Algorithms are usually written in English and some few mathematical notations (signs, symbols)

Characteristics of Algorithms

  1. They are written in sequence.
  2. They are written in English-like statements.
  3. Finite, it must have a beginning and an end.
  4. Should be effective
  5. Should not be ambiguous. Should be consistent.
