A Guide to Working with Visual Logic - Vocabulary Flashcards

Vocabulary flashcards covering key Visual Logic concepts from the lecture notes.

Input-Process-Output (IPO) Model

A framework where data is input, processed, and output as information.

Algorithm

A step-by-step procedure used to solve a problem in programming.

Flowchart

A visual diagram showing the sequence of steps and decisions in an algorithm.

Pseudocode

A high-level, human-readable outline of an algorithm that resembles code but is not executable.

Visual Logic

A visual tool that combines flowcharts and pseudo-like syntax to model algorithms; not a true programming language.

Input statement

A statement that reads data from the user and stores it in a variable.

Output statement

A statement that displays data to the user (in a window, console, or file).

Variable

A named memory location that stores a value and can change during execution.

Identifier

The name assigned to a variable; must not contain spaces; letters, numbers, and underscores allowed; Visual Logic is case-insensitive.

Legal identifiers

Identifiers that follow the rules (e.g., NAME, num1, interestRate, Num1, Num2) and have no spaces.

String input

Input data that must be enclosed in quotation marks.

Numeric input

Input data that must contain only digits and may include one decimal point.

Assignment statement

A processing step that evaluates the right-hand side and stores the result in the left-hand side variable.

Left-hand side (LHS)

The variable on the left side of an assignment that receives the value.

Right-hand side (RHS)

The expression on the right side of an assignment whose value is assigned.

FormatCurrency

An intrinsic Visual Logic function that formats a value as currency with a leading dollar sign and two decimal places.

Begin/End

Keywords that mark the start and end of a Visual Logic program flow.

Input flowchart symbol (Parallelogram)

The parallelogram shape used in Visual Logic to denote an input operation.

Processing rectangle

The rectangular flowchart symbol used to denote assignment/processing steps.

Internet Shopping Cart System (example)

A sample Visual Logic project illustrating steps like database connection, product cost, tax calculation, billing, receipts, and reports.
