Constructor Chain Trace

Constructors run from the top of the hierarchy down. A's constructor prints A constructor. Create B : A whose constructor prints B constructor, and C : B whose constructor prints C constructor. Because base constructors run first, creating a C prints all three lines top-down. Do NOT write a Main method.

When the tester creates a C, the program prints the output shown in Expected Output.

Expected Output:

A constructor↵
B constructor↵
C constructor↵

= newline. The output ends with a newline — print one after the last line.
