Algorithm Design And Problem-solving
Akopọ
Before a single line of code is written, a good programmer has a plan: they break the problem into parts, design each part as an algorithm, decide how to test it, and check it works by tracing it by hand. This topic is the toolkit every programmer uses to turn a vague problem into a working, reliable solution.
You will learn the program development life cycle, how to decompose a problem into sub-systems, the standard methods such as totalling, counting and finding the maximum and minimum, validation and verification checks, how to choose good test data, how to complete a trace table for a dry run, and how to find and fix errors in algorithms. Pseudocode here follows the Cambridge 0478 conventions. By the end you should be able to write, trace and correct algorithms with confidence.
Awọn Afojusun
- 1 Understand the program development life cycle, limited to: analysis, design, coding and testing
- 2 (a) Understand that every computer system is made up of sub-systems, which are made up of further sub-systems (b) Understand how a problem can be decomposed into its component parts (c) Use different methods to design and construct a solution to a problem
- 3 Explain the purpose of a given algorithm
- 4 Understand standard methods of solution
- 5 (a) Understand the need for validation checks to be made on input data and the different types of validation check (b) Understand the need for verification checks to be made on input data and the different types of verification check
- 6 Suggest and apply suitable test data
- 7 Complete a trace table to document a dry-run of an algorithm
- 8 Identify errors in given algorithms and suggest ways of correcting these errors
- 9 Write and amend algorithms for given problems or scenarios, using: pseudocode, program code and flowcharts
