Question

quiz 3 - loops
consider the following code:
x = 0
y = 0
repeat 3 times:
repeat until y = 3:
y = y + 1
x = x + 1
y = 0
display(x)
what output will be displayed?

Explanation:

Step1: Analyze inner - loop

The inner loop Repeat until y = 3: increments y by 1 each time until y reaches 3. Each iteration of the inner loop also increments x by 1. Since y starts at 0, the inner - loop will execute 3 times, and x will be incremented 3 times in one execution of the inner - loop.

Step2: Analyze outer - loop

The outer loop Repeat 3 times: means the inner - loop (along with the subsequent y = 0 statement) will be executed 3 times. Each time the inner - loop runs, x is incremented 3 times. So in total, x will be incremented $3\times3 = 9$ times.

Answer:

9
