1. WRITING AN ALGORITHM, PSEUDOCODE, AND FLOWCHART LESSON 2

2. OBJECTIVES SHOULD BE ABLE TO explain what an algorithm, pseudocode and flowchart are; Recognize the important of an algorithm, pseudocode, and flowchart; Create an algorithm, pseudocode, and flowchart.

3. THINK ABOUT IT! Following instructions in a cookbook is same as following instructions using an algorithm, pseudocode, or flowchart. These are programming tools that show the step-by-step procedure in solving computer programs.

5. WHAT IS ALGORITHM?

6. ALGORITHM An algorithm is a step-by-step procedure to solve the problems. It makes the whole procedure more efficient and consistent. It also helps in identifying decision points, processes, and essential variables to solve the problem. A programmer can also see and determine easily the errors in a particular process using algorithm.

7. WHAT IS PSEUDOCODE?

8. PSEUDOCODE A pseudocode is a description of an algorithm using natural language, which makes reading of the program easier. It uses short English-like statements to write codes for programs before you actually create it in a specific language.

9. WHAT IS A FLOWCHART?

10. FLOWCHART A flowchart is a diagram presenting the logical sequence in which a combination of steps or operations is to be performed.
