Questions and Answers

What is a key rule in creating program flowcharts?

Only standard symbols must be used. (correct)

Symbols should be colored differently for clarity.

Flowcharts should be unreadable to maintain complexity.

More than one exit point is needed for each symbol.

How should the flow of a program be shown in a flowchart?

From bottom to top and right to left.

Randomly, to show flexibility in the program's logic.

In a circular format for better visualization.

From top to bottom and/or left to right. (correct)

What is the maximum number of entry and exit points permitted for a symbol in a flowchart?

Two entries and two exits are optimal for maximum clarity.

More than one entry and exit point is allowed.

Only one entry and one exit point per symbol, except decisions. (correct)

No restrictions on entry and exit points.

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.
