Programming Fundamentals/Loop Examples

Counting Pseudocode ... This program demonstrates While, Do, and For loop counting using user-designated start, stop, and increment values. Function Main Declare Integer start Declare Integer stop Declare Integer increment Assign start = GetValue("starting") Assign stop = GetValue("ending") Assign increment = GetValue("increment") Call WhileLoop(start, stop, increment) Call DoLoop(start, stop, increment) Call ForLoop(start, stop, increment) End Function GetValue (String name) Declare Integer value Output "Enter " & name & " value:" Input value Return Integer value Function WhileLoop (Integer start, Integer stop, Integer increment) Output "While loop counting from " & start & " to " & stop & " by " & increment & ":" Declare Integer count Assign count = start While count <= stop Output count Assign count = count + increment End End Function DoLoop (Integer start, Integer stop, Integer increment) Output "Do loop counting from " & start & " to " & stop & " by " & increment & ":" Declare Integer count Assign count = start Loop Output count Assign count = count + increment Do count <= stop End Function ForLoop (Integer start, Integer stop, Integer increment) Output "For loop counting from " & start & " to " & stop & " by " & increment & ":" Declare Integer count For count = start to stop step increment Output count End End Output Enter starting value: 1 Enter ending value: 3 Enter increment value: 1 While loop counting from 1 to 3 by 1: 1 2 3 Do loop counting from 1 to 3 by 1: 1 2 3 For loop counting from 1 to 3 by 1: 1 2 3 Flowchart 400px|top|Loops main flowchart 250px|top|Loops Get Value flowchart 400px|top|Loops While Loop flowchart 400px|top|Loops Do Loop flowchart 400px|top|Loops For Loop flowchart References Wikiversity: Computer Programming
