"Question $1$: Write the two C$++$ statements necessary to create an object of type FirstClass and store its address in a er to class SecondClass. SecondClass is the base class to FirstClass. Both variables must be declared.

Do not write any other code except what is required to answer this question. Do not write an entire program. You must use the identifiers specified in the instructions.

Question $2$: A derived class $\_\_\_\_\_\_\_\_$ a function in its base class when it implements that function differently.

Do not write code. Do not write anything except the one word required to answer this question.

Question $3$: Write the complete prototype for a function QO$03$ called functionA in a base class called BaseClass. This function has no parameters or return value. Derived classes of BaseClass will create specific implementations for this function. In a driver program, BaseClass ers may at a derived$-$class objects, and the derived class version of functionA must execute.
