TUTORIAL: INTRODUCTION TO PROGRAMMING (part2)

PROGRAMMING TOOLS (ALGORITHM AND FLOW CHART)

1. ALGORITHM

 This is a step by step approach towards solving a particular problem.

CHARACTERISTICS OF AN ALGORITHM

i. Finiteness

ii Effectiveness

iii Definiteness

iv Output

v Input

vi Generality.

2. FLOW CHART

This is the graphical representation of an algorithm.

STEPS IN WRITING COMPUTER PROGRAMS

1. Problem definition.

2. Problem Analysis.

3. Developing the solution (Solution Analysis): Develop an algorithm

4. Coding: Convert the algorithm into a computer program.

5. Testing and debugging.

6. Documentation.

7. Implementation.
