1. Using the top–down method, please describe an algorithm for a program to solve the real roots of a quadratic equation ax2 + bx + c = 0 Your algorithm should ask the user for the coefficients. To calculate the roots of the equation, Your algorithm should calculate the discriminant D given by D = b2 – 4ac. If D > 0, the algorithm displays a message: The equation has two roots and then displays the roots. If D = 0, the algorithm displays a message: The equation has one root, and then displays the root. If D < 0, the algorithm displays a message: The equation has no real roots. Create a flowchart for your algorithm.

Write a program that reads a file consisting of students’ test scores in the range 0–200. it should then determine the number of students having scores in each of the following ranges: 0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200. output the score ranges and the number of students. (run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189.)

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
