The statement y.get2( ); will
a) return 5b) return 6
c) return 3
d) return 0
e) cause a run-time error
Consider a class that stores 2 int values. These values can be assigned int values with the messages set1(x) and set2(x) where x is an int, and these values can be accessed through get1( ) and get2( ). Assume that y and z are two objects of this class. The following instructions are executed:
y.set1(5);
y.set2(6);
z.set1(3);
z.set2(y.get1( ));
y = z;
Answer: a.
Explanation: The statement y = z; causes y and z to be aliases where y.get2( ); returns the same value as z.get2( );. Since z.set2(y.get1( )); was performed previously, z and y's second value is 5.
