Overview
In this lesson, we will explore loops in pseudocode. Loops are fundamental programming constructs used to repeat a block of code multiple times. Understanding loops is crucial for automating repetitive tasks and managing complex data operations in programming.
Objectives
By the end of this lesson, you will be able to:
- Understand the concept and purpose of loops.
- Differentiate between
forandwhileloops. - Write pseudocode using loops for repetitive tasks.
What are Loops?
Loops are used in programming to execute a block of code repeatedly as long as a specified condition is met. They are essential for tasks that require repetition, such as calculating sums, iterating over arrays, or processing user input.
Types of Loops
- For Loop: Used when the number of iterations is known beforehand. It repeats a block of code a specific number of times.
- While Loop: Used when the number of iterations is not known in advance. The loop continues as long as a specified condition is true.
For Loops
Structure of a For Loop
Example: Printing Numbers from 1 to 5
While Loops in Pseudocode
Structure of a While Loop:
Example: Repeating User Input Until ‘Exit’
Practice Exercises
Exercise 1: Counting Even Numbers
Exercise 2: User-Driven Counter
