A character string is set up once and never changes during program execution.

Question 23

The steps within each CASE path are always grouped together in a module.

Question 24

The top-to-bottom arrangement of the conditions in the CASE control structure dictates the actual order that the tests will be made by the computer.

Question 25

The pseudocode form of a CASE control structure always contains exactly three levels of indentation regardless of how many tests are made.

Question 26
