Question 8

Consider the following constructor:

student (string n, int k)

{

name = n;

no_of_tests = k;

marks = new double [k];

for(int i = 0; i<k; i++)

{

cout << " Enter grade #: "<< i << endl;

cin >> marks[i];

  }

Write a destructor for the constructor above.

Question 9

Write a program that ask the user for coefficients a, b, and c of a quadratic equation (ax^2 + bx + c = 0) and return the solutions.

Show me that you wrote it yourself through details, structure, and comments in your code. Remember that a quadratic equation may have one real solution, or two reals solutions, or two complex solutions; a complex number has the form x + yi.

Question 10

Using classes,data, methods and constructors, Write a program that ask the user for:

deposit P

interest rate r

how often the interest is compounded n

years after which they are collecting the total amount t

The program returns the amount colleted A, when P has been deposited into an saving account with interest r compounded n times per year, for t years.

The equation is: A = P*(1 + r/n)^nt
