Study Notes
Problem Analysis and Solution
- Breaking down a complex problem into simpler parts enables easier programming and organization of the solution.
- The problem analysis chart (PAC) is used to consolidate data for a problem, and it consists of four parts: given data, required results, processing required, and solution alternatives.
IPO Chart
- The IPO (Input-Processing-Output) chart extends and organizes the information in the problem analysis chart.
- It shows the input data, processing, and output information, including where the processing takes place.
Algorithms
- Algorithms are sets of instructions for the computer, developed from the IPO chart and structure chart.
- Each module in the structure chart has a separate set of instructions.
- Algorithms must be complete, executable one step at a time, and cannot assume anything or skip steps.
Flowcharts
- Flowcharts are graphic representations of algorithms.
- They are used to test the solution for bugs and to code the problem into a computer language.
- Flowcharts can show errors in logic not readily visible in other charts.
Pseudocode
- Pseudocode is similar to an algorithm, but without numbers and condensed.
- It is used to develop the instructions for each module in the solution.
Internal and External Documentation
- Internal documentation consists of remarks written with the instructions to explain the program.
- External documentation includes manuals or help menus written about the solution.
Communicating with the Computer
- Computers do not understand English, so programmers must learn the computer's language.
- Incorrect instructions can result in error messages, wrong answers, or no answer at all.
- Syntax refers to the rules governing the computer operating system, language, and application.
- Errors are called bugs, and debugging is the process of finding and correcting them.
Organizing the Solution
- A programmer uses various tools to organize the solution, including:
- Problem analysis chart
- Structure chart or interactivity chart
- IPO chart
- Algorithms
- Flowcharts
- Pseudocode
- These tools help to create a more efficient and readable solution.
Analyzing the Problem
- A good way to analyze a problem is to separate it into four parts: given data, required results, processing required, and solution alternatives.
- The problem analysis chart is used to analyze the problem and set up the most efficient solution.
Interactivity Chart
- The interactivity chart (structure chart) divides the processing into subtasks called modules and connects them to show the interaction of processing between the modules.
- Each module should contain tasks to accomplish one function, such as entering data, printing results, or calculating results.
- One module controls the flow to most of the other modules, known as the Control or Main module.
