Algorithms, Pseudocode, and Flowchart Review Quiz

Algorithm Pseudocode and Flowcharts

• The START and STOP statements in algorithm pseudocode indicate the beginning and end of the program.

Flowchart Symbols

• The terminal or end of the process in a flowchart is represented by the oval shape symbol.

READ Statement

• The 'READ' statement in algorithm pseudocode is used to read input from the user or keyboard.

Conditional Statements

• The 'IF-ELSE' statement in algorithm pseudocode is used to make decisions based on conditions and execute different blocks of code accordingly.

Looping Statements

• The 'REPEAT UNTIL' statement in algorithm pseudocode is used to repeat a block of code until a specified condition is met.

Algorithm Pseudocode and Flowchart Examples

Welcome Program

• Algorithm pseudocode:
• START
• PRINT "Welcome to my program"
• READ first_name
• PRINT "Nice to meet you Mr. " + first_name
• STOP
• Flowchart:
• Oval shape: START
• Rectangle: PRINT "Welcome to my program"
• Diamond: READ first_name
• Rectangle: PRINT "Nice to meet you Mr. " + first_name
• Oval shape: STOP

Rectangle Area Problem

• Algorithm pseudocode:
• START
• READ length
• READ width
• area = length * width
• PRINT "The area of the rectangle is " + area
• STOP
• Flowchart:
• Oval shape: START
• Rectangle: READ length
• Rectangle: READ width
• Diamond: area = length * width
• Rectangle: PRINT "The area of the rectangle is " + area
• Oval shape: STOP
