COMPUTER SCIENCE Verified answer COMPUTER SCIENCE Write the declaration for class B. The class’s members should be - m, an integer. This variable should not be accessible to code outside the class or to member functions in any class derived from class B. - n, an integer. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class B. - setM, getM, setN, and getN. These are the set and get functions for the member variables m and n. These functions should be accessible to code outside the class. - calc, a public virtual member function that returns the value of m times n. Next write the declaration for class D, which is derived from class B. The class’s members should be - q, a float. This variable should not be accessible to code outside the class but should be accessible to member functions in any class derived from class D. - r, a float. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class D - setQ, getQ, setR, and getR. These are the set and get functions for the member variables q and r. These functions should be accessible to code outside the class. - calc, a public member function that overrides the base class calc function. This function should return the value of q times r.

COMPUTER SCIENCE The Fibonacci sequence of numbers is defined as follows: The first and second numbers are both 1. After that, each number in the sequence is the sum of the two preceding numbers. Thus, the Fibonacci sequence is as follows: $1,1,2,3,5,8,13,21, \ldots$ If F(n) stands for the nth value in the sequence, then this definition can be expressed as: F (1) = 1; F (2) = 1; F(n) = F (n − 1) + F (n − 2) for n > 2; a. Using the definition of the Fibonacci sequence, compute the value of F (20). b. A formula for F (n) is $$ F(n)=\frac{\sqrt{5}}{5}\left(\frac{1+\sqrt{5}}{2}\right)^{n}-\frac{\sqrt{5}}{5}\left(\frac{1-\sqrt{5}}{2}\right)^{n} $$ Using the formula (and a calculator), compute the value of F (20). c. What are your opinions on the relative clarity, elegance, and efficiency of the two algorithms (using the definition and using the formula) to compute F (20)? Would your answer change if you considered F(100)? Verified answer Recommended textbook solutions
