Question

3. Trace through the following loop and show the values for MiceOrdered, MiceSent, and MiceUsed. Declare MiceOrdered = 12 Declare Mice Sent = 8 Declare MiceUsed = 0 Declare MiceTested = 4 Do Until MiceOrdered = MiceSent If MiceOrdered - MiceSent <> 0 MiceUsed = MiceUsed + 1 MiceOrdered = MiceOrdered - 1 Endif MiceTested = Mice Tested + 1 End Do

I need each one value

Answer 1

The loop will execute until MiceOrdered becomes equal to MiceSent i.e. the loop will keep executing till both the values MiceOrdered and MiceSent becomes equal to each other.

So initial values of variables are:

MiceOrdered = 12
MiceSent = 8
MiceUsed = 0
MiceTested = 4

As, the values of MiceOrdered(12) and MiceSent(8) are not equal now, so loop will execute. The change in all the values due to loop is shown below table:

9 Iteration Mice Ordered Micesent Mice Used Mice Tested 00 Initial Values It 1: IJs og oop og & Nool 08 As Mice Ordered = Mice sent you, so the loop will stop here Hence, final values are : Value of Mice Ordered: 8 1 Value of Mice sent : 8 value of Mice Used : 4 I Value of Mice Tested : 8

It denotes iteration number.
