Study Notes
System Flowcharts
- System flowcharts visualize how different components of a system interact, highlighting data flow and decision points.
- Different shaped boxes represent various operations, with arrows indicating the flow direction to the next step.
Standard Flowchart Symbols
- Terminal: Indicates the start and end of processes.
- Input/Output: Represents any input or output operations.
- Computer Processing: Depicts processing tasks performed by a computer system.
- Predefined Processing: Indicates processes not specifically defined in the flowchart.
- Comment: Used for explanatory notes to clarify flowchart details.
- Flow Line: Connects the various symbols in the flowchart.
- Document Input/Output: Denotes input from a document and output directed to a document.
- Decision: Marks points where decisions must be made for further actions.
- On-page Connector: Connects sections of a flowchart continued on the same page.
- Off-page Connector: Connects sections continued on separate pages.
Rules for Creating Program Flowcharts
- Only standard symbols should be utilized in flowchart designs.
- Flow of program logic must move from top to bottom and/or left to right.
- Each symbol should have one entry and exit point, with the exception of decision symbols.
- Operations within symbols should be independent of any specific programming language.
- All decision branches must be clearly labeled.
Factors in Choosing a Programming Language
- Consider project requirements and performance needs.
- Evaluate community support and the availability of libraries or frameworks.
Programming Terminologies
- Syntax: Set of rules for symbol or character arrangements to create valid statements.
- Command: Unique instruction given to execute a specific function (e.g., “print”).
- Integrated Development Environment (IDE): Software application for code formatting, syntax checking, and running/testing code; may support multiple languages.
- Library: Collection of resources and functions that can be utilized individually, typically pre-built in an IDE.
- Interpreter: Executes high-level language instructions directly without machine code conversion.
- Assembler: Converts low-level assembly code into machine language.
- Compiler: Translates high-level languages into machine-readable code.
Algorithms in Programming
- An algorithm consists of a sequence of computational steps to solve a problem.
- Must be expressed in a comprehensible manner, such as natural language.
- Example of algorithm for calculating volume of a rectangle:
- Obtain length, width, and height.
- Use the formula: volume = length × width × height.
