Example Code Ch 13-6
Assume a stack class stores int values. Consider the following sequence of instructions.
Stack s = new Stack() ;
s.push(16) ;
s.push(12) ;
s.push(19) ;
int x = s.pop() ;
s.push(5) ;
s.push(9) ;
s.push(4) ;
int y = s.pop() ;
int z = s.pop() ;
-Refer to Example Code Ch 13-6: After the instructions execute, x has the value

A) 16
B) 12
C) 19
D) 0
E) None of these; the instruction int x = s.pop() results in an exception being thrown
