Computer Science

the process of placing one loop inside another loop

the loop that contains another loop inside it

the loop that is placed inside another loop and runs completely each time the outer loop runs once

Nested loops

In this unit pupils discover how iteration is used to replicate parts of a program. They will analyse the difference between count and condition controlled iteration and how trace tables can be used to trace through loops. They will explore data validation techniques and robust program design.

Programming: iteration

What happens to the inner loop when the outer loop runs again?

`for i in range(5): for j in range(3): print(i, j)`

Which of these is an example of a nested loop?

to repeat a process within another process

What happens if the outer loop in a nested loop has a range of 0?

Arrange the output for the following code:

```for i in range(2):  
    for j in range(3):  
        print(i, j)```

the process of converting code into machine language

the process of repeating a sequence of instructions

a loop that runs while a condition is True

a loop that repeats for a specific number of times

Which Python statement is used for count-controlled iteration?

What does the `range()` function do in Python?

Which Python statement is used to repeatedly execute a block of code as long as a condition remains True?

It helps convert code to machine language.
