Iteration
Iteration
Iteration allows a group of statements to be repeated multiple times. Iteration statements are often called loops.
Indefinite iteration
Indefinite iteration
- A block of code will repeat whilst a specified condition is true.
- For example: the while loop will continue to execute an indented code block while a certain condition is true.
Definite iteration
Definite iteration
- A block of code will repeat a known number of times.
- For example: a for loop will execute an indented block for each value in a list of values.
Flow diagram
Flow diagram
- A flow diagram for iteration uses the diamond shape.
