Programming I - Flowchart and Algorithms

These flashcards cover key vocabulary and concepts related to flowcharts and algorithms as presented in the lecture notes.

Algorithm

A sequence of steps that describes how to solve a problem.

Flowchart

A graphical representation of an algorithm that uses symbols to show the flow of information and processing.

Terminal Symbol

Symbol represented by a rounded rectangle that indicates the start and end points of an algorithm.

Input/Output Symbol

Symbol represented by a parallelogram that indicates input or output operations.

Selection Symbol

Symbol represented by a diamond that shows a decision point with two possible paths based on a condition.

Process Symbol

A rectangle that indicates an operation or instruction, such as mathematical computation or variable assignment.

Flow Line

Arrows in a flowchart that indicate the direction of flow of control and the sequence in which instructions are executed.

Connector

A small circle used in flowcharts to connect two segments that may not fit on the same page.

Repetition Structure

A part of a program that repeats actions based on a condition, also known as a loop.

Pre-Test Repetition

A repetition structure where the condition is tested before any actions are performed.

Post-Test Repetition

A repetition structure where the condition is tested after the action has been performed.

Decision Structure

A control structure where one of two possible actions is taken based on a condition.

Sequence Structure

Structure where program execution flows sequentially from top to bottom without skipping or repeating statements.

Basic Flowchart Symbols

Standardized symbols used to represent different types of actions or processes in a flowchart, such as terminal, process, input/output, and selection symbols.

Example of Flowchart

A practical demonstration of how to read numbers, perform calculations, and display results in a flowchart format.

Infinite Loop

A loop that continues indefinitely because the terminating condition is never met.

Average Calculation

The process of computing the average value from a given set of numbers.
