The answer to this puzzle can be anything but most commonly it is Trees. Pines, Redwood, Sequoias, any kind that is tall and straight. Or it can be something like poles, or even humans.
Answer:
FALSE
Explanation:
Because C1 and C2 implement the same interface, they both implement whichIsIt. The variable c is known as a polymorphic variable, meaning that it can change from being an C1 to a C2. So, the message c.whichIsIt( ); may invoke C1's whichIsIt or C2's whichIsIt. This can only be known at runtime.
Answer:
False
Explanation:
This is not true at all. This can be done with a wide variety of resources in the modern world. There is the CPLEX (IBM ILOG CPLEX Optimization Studio) software, which was developed by Robert E. Bixby in 1988, it passed to several other companies and it was later sold to IBM in January 2009. Today it's one of the world's most effective programs when it comes to automated linear programming solutions.
