Question 3

Console outputs that you are required to write your code to exactly match them are written at the very end of the paper. Q4, Q5 and Q6 looks dependent in the code below. However, they will be evaluated on their own with their own input. That means, if you cannot solve Q4, Q5 will be tested with its intended input coming from a correct Q4 solution. The same situation applies to Q6 as well. Q6 will be tested with its intended input coming from a correct Q5 solution. Remember that we'll test your code with different inputs! Copy the code below to your editor and create midterm2.cpp" file and start solving it. // StudentID: xxxxxxxx, Name: AAA BBB CCC #include #include #include #include 1/ CAREFUL! + Do not use "using namespace std;".
