Question

consider the following code. repeat until x > 10 x ← x * 2 display x assuming that before this code is run, x = 1. what would be displayed at the end?

Explanation:

Step1: Initial value

Given \(x = 1\).

Step2: First - iteration

\(x=x\times2=1\times2 = 2\), and \(2<10\), so continue.

Step3: Second - iteration

\(x=x\times2=2\times2 = 4\), and \(4<10\), so continue.

Step4: Third - iteration

\(x=x\times2=4\times2 = 8\), and \(8<10\), so continue.

Step5: Fourth - iteration

\(x=x\times2=8\times2 = 16\), and \(16>10\), stop the loop.

Answer:

16
