Score

As you can see, I scored a 57/67 on the 2018 MCQ (85%)

Reviewing Questions that I missed:

The program initializes x to 2, then multiplies it by 3 a total of four times.

Overflow errors occur when an arithmetic operation results in a value outside the range of numbers that can be represented by a fixed number of bits.

Program I correctly moves the robot to the gray square by repeatedly moving the robot forward, rotating left, moving forward twice, and rotating right. Program II correctly moves the robot to the gray square by moving the robot forward to the bottom right corner of the grid, rotating left, moving the robot forward to the upper right corner of the grid, rotating left, and moving forward to the gray square.

Program A initializes i to 1. Inside the loop, it prints i and then increments i. The loop terminates when i is greater than 10, which occurs after 10 is printed. Program A prints 1 2 3 4 5 6 7 8 9 10. Program B initializes i to 0. Inside the loop, it increments i and then prints i. The loop terminates when i equals 10, which occurs after 10 is printed. Program B prints 1 2 3 4 5 6 7 8 9 10.

The files that are up to 10 MB represent 17% + 24% + 25% + 10%, or 76%.

This code segment takes the sum of the individual scores and subtracts the lowest score. To obtain the average, the result is divided by one less than the number of scores (since one score was dropped).

Certificate authorities are entities that issue digital certificates, which are used to certify the ownership of public keys.

If the connections between U and V and between U and P were removed, then computer T and computer U can no longer communicate.

Answer is B and C, not C and D. This code segment stores the substring “lope” in animal. It then concatenates “a” and “lope”, storing the result “alope” in animal. Lastly, it concatenates the substring “jack” and “alope”, storing the result “jackalope” in animal.
