Question

which is not a good use of a perfect size array? a. university student ids b. names of the week c. names of the months d. names of marker colors in a box of 8

Answer 1

a. University student ids

Array sizes can't be manipulated without a lot of extra work, so you want the amount of data to be the static. The amount of university student ids will be changing with students coming and going.

Note that you can change the data stored at an index in an array easily but changing the size of the array is difficult.
