1. A class Linear is defined as follows.
class Linear {
pr ivate :
double a0 ;
double a1 ;
pub l ic :
Linear (double , double) ;
double substitute (double) ;
void display () ;
} ;
Linear represents a linear expression in the form of
a0x + a1. (1)
In other words, a0 and a1 are a0 and a1 respectively in the class definition. The function substitute
computes and returns the value of (1) when x is substituted by the input argument of substitute.
The display function displays the expression (1) in the form of
a0 + a1*x
Write
(a) the two-argument constructor,
(b) the member function substitute and
(c) the member function display
of Linear.
Then derive Quadratic from Linear to handle quadratic expression objects in the form of
a0 + a1x + a2x
(2)
Include a2 of type double as the private member of Quadratic. Provide a three-argument constructor
for Quadratic. Override the member functions substitute and display. The substitute function
in Quadratic evaluates and returns (2) by substituting the value passed into the equation. The display
function of Quadratic prints the quadratic expression in the form of
a0 + a1*x + a2*x^2
Utilize the functions in Linear whenever possible. Explain how a product between two linear expressions can be computed in your program. In which class should the calculation be done?

Consider the following statements, then select one of the answers below: the signal() function shown below registers "sig_handler()" as the signal handler function for the sigkill signal, without the complexity of using when the sigkill signal is sent to a process running this code, by a user typing "kill -kill ", where the correct process id is used for to target the process, sig_handler() will be executed.

1. ask the user how many questions are in the quiz. 2. ask the user to enter the key (that is, the correct answers). there should be one answer for each question in the quiz, and each answer should be an integer. e.g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. you will need to store the key in an array. 3. ask the user to enter the answers for the quiz to be graded. there needs to be one answer for each question. note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. 4. when the user has entered all of the answers to be graded, print the number correct and the percent correct. 5. add a loop so that the user can grade any number of quizzes with a single key. after the results have been printed for each quiz, ask "grade another quiz? (y/n)." note: you only have one array (the key). you are not creating a new key for each set of quiz answers.
