Add two polynomials

Given two polynomials A and B, write a program that adds the given two polynomials A and B

Output

Print the addition of polynomials A and B.

If the degree of polynomial is zero and the constant term is also zero, then just print 0 to represent the polynomial.

What is the subject statement of 496.39282491431 in Dewey Decimal classification?

Write a program that first requests from the user how many integers will be entered. It then reads 

in those integers and calculates and displays the average of the numbers (to the nearest 2 

decimal points). It must cater for a scenario where the user enters 0 numbers.

Write a program which requests a number between 1 and 50 from the user. It must repeatedly ask 

the user for a number until a valid number is entered. 

After receiving a valid number, the program must display all the even numbers smaller than that 

number. (If the user enters 11, the numbers 2,4,6,8,10 must be displayed)

Write a program that does the following for 15 students:

 Reads in 3 marks for each student (marks must be between 0 and 100)

 Calculates and displays the highest mark for each student.

 Finds the highest mark for all students

Write a program to create a base class: “Question3”, with protected data member: x (int) and with pure virtual function: “Task ()” [Returns no value and takes no argument]. Create a derived class of “Question3” such as “Sub1” (Derive features in public mode). In sub1, there is a member function in public section: get_data1 () to take input for x, and define Task () in this class to display the reverse of x. [Implement the above program by creating pointer to base in main () function and call the necessary functions].
