VITTA SD 2011 exam #2 - C6a/b/c<br><br>There's another deliberate logical error in the pseudocode that makes itself shown in 1344's actual total fare. It's not specifically asked about in the paper, but students might suggest it as an algorithmic fault in C6b and C6c.<br>
<br>The very first record processed is not counted as a trip because LastCustomerID is initialised as blank and does not match the NextCustomerID in the very first record. This explains why the actual total is $2 less than the expected total. <br>
<br>You might want to add a question to see if kids can explain the discrepancy in customer 1344's actual total fare. <br><br>Keep in mind that customer 1344's expected and actual fares should both be $2 less than they are in the solution because there are only 2 trips for that customer, not 3 as far as I can tell.<br>

Hi all. Playing with Section C, Q6a, customer 1344 is said in the solution to expect a $6.00 total fare, but I can only see 2 trips taken by that person, which would give an expected total of $4.00.<br><br>Can someone confirm this?<br clear="all">
<br>People using this exam will also need to note that the answers to these questions will change over time because the people's birthdates are used rather than their raw ages. So the troublesome 16 year old is now 17 in 2012, and is beyond the boundary condition! You might want to replace DOBs with raw ages instead.<span class="HOEnZb"><font color="#888888"><br>
