Study Notes
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
