A virtual function is a function member of a class,
declared using the "virtual" keyword. A pointer to a
derived class object may be assigned to a base class
pointer, and a virtual function called through the pointer.
If the function is virtual and occurs both in the base
class and in derived classes, then the right function will
be picked up based on what the base class pointer "really"
points at.

Question: Write a program that prints a paycheck. Ask the program user for the name of the employee, the hourly rate, and the number of hours worked. If the number of hours exceeds 40, the employee is paid “time and a half”, that is, 150 percent of the hourly rate on the hours exceeding 40. Be sure to use stepwi se refine ment and break your solution into several functions. Use the int_name function to print the dollar amount of the check.

Write a program to compute for numeric grades for a course. The course records are in a file that will serve as the input file. The input file is in exactly the following format: Each line contains a student's first name, then one space, then ten quiz scores all on one line. The quiz scores are in whole number and are separated by one space. Your program will take it input from this file and sends it output to a second file. The data in the output file will be exactly the same as the data in the input file except that there will be one additional number (of type double) at the end of each line. This number will be the average of the student's ten quiz scores. Use at least one function that has file streams as all or some of its arguments.
