Q1) Write a program which will permit teacher to compute the percentage and the final grade for students in a class. The program will prompt the teacher to enter the student's first and last name and the number of points the student received. The program shall only accept scores between 0 and 1,000 points (including 0 and 1,000), with 1,000 points being the maximum number of points. If the input value is within the valid range, the program will display a "good score" message; otherwise, the program will display an error message and then terminate the program.
