In this guide we will be covering For loops in pseudocode, While loops in pseudocode and even Do loops in pseudocode. What can loops be used for in pseudocode? If you want to repeat a certain piece of code a certain number of times, that is exactly where loops help you.

Use case - e.g. looping while neither player has won the game. REPEAT...UNTIL (post-conditional): executes code, then checks condition - loops while condition is FALSE. Will always execute at least one time, since condition is checked after that initial execution.

Use a FOR loop when you know exactly how many times you want to repeat a block of code. Use a WHILE loop when the number of iterations is not known in advance or depends on a condition. Remember, the goal of pseudocode is to communicate logic clearly.

Jul 16, 2020 · Use string splitting to cut the input up and then loop through that list with for, while, do, until, or etc. Create a sum total variable and add each input value to it, e.g. sum = sum + split_input[index], or if it will only allow a single input at a time sum = sum + input.

Write pseudocode using a WHILE loop to input 5 numbers and find how many are positive and how many are negative.

In pseudocode, there are three primary types of loops: FOR, WHILE, and REPEAT. Each serves different use cases, and understanding when to use each is key to writing efficient code. This guide covers these loops step-by-step, from simple examples to more complex scenarios involving options like stepping through ranges or using nested loops.

Mar 28, 2025 · Core pseudocode constructs. Programming logic flows through sequences, decisions and loops. The following pseudocode constructs, each supplemented by a general workflow example, form the basis of algorithmic problem-solving and enable developers to model real-world processes -- from edge case troubleshooting in algorithm behavior to creating phased implementation roadmaps that balance ...

Sep 4, 2024 · This loop iterates through the numbers 1 to 5 and prints each one. 3. WHILE Loop Example: Print Numbers from 1 to 5 START SET i TO 1 WHILE i <= 5 DO PRINT i INCREMENT i BY 1 END WHILE END ...

While Loop: Used when the number of iterations is not known in advance. The loop continues as long as a specified condition is true. Example: Printing Numbers from 1 to 5. Structure of a While Loop: Example: Repeating User Input Until ‘Exit’. Exercise 1: Counting Even Numbers. Exercise 2: User-Driven Counter.

In this lesson you will learn how to use while loops in pseudocode to repeat sequences of instructions. Video. The video below (3:00 mins) provides an overview of while loops.
