Flow Charts..
A flowchart is a visual way to represent a process using symbols and lines. It helps show the steps in a clear sequence, making complex ideas easier to understand. People use flowcharts in business, programming, and other areas to map out processes and make decisions.
Flow Chart Symbols..
- Flow Lines
It shows the flow control through he program.
- Terminal Symbol
Its used to indicate beginning and end.
- Input Output Symbol
Its used to indicate both input and output.
- Process Symbol
Indicates using a rectangle and represents calculations and initialization of memory locations.
- Preparation Symbol
Its used for any initialization done, usually at the beginning of a program.
- Decision Symbol
There will always be two exits from a decision symbol, labeled as YES /NO or TRUE/FALSE.
- Connector
Its used to connect the flow charts to represent its' continuation.
Example of flow chart..
Pseudocode..
Pseudocode is a high-level, informal representation of a computer program or algorithm that combines elements of programming language syntax with plain language. It serves as a tool for planning and designing software logic before actual coding, providing a readable and abstract description of the intended program flow.
- Rules for Pseudocode
☛ Capitalize initial key word.
☛ Indent to show hierarchy.
☛ End multiline structures.
☛ Keep statements language independent.
Algorithm..
An algorithm is a precise set of instructions or rules designed to perform a specific task or solve a particular problem. In the context of computer science, algorithms serve as systematic approaches to computation, guiding the step-by-step process of achieving desired outcomes in software and problem-solving.
