Write a program to work with rectangles. The following main menu must
be repeated until ‘0’ (zero) is entered. When the first or second menu is
selected, the program will ask for the value via a message such as “Enter the
length:”, assign the value to the variable, and display the confirmation
message such as “The length is set at: 10”. When the third menu is selected,
the program will display a message such as “The area of a 10 x 20 rectangle is:
200.” If the user enters any other number, the program should display a message
such as “Invalid input. Try again.”

Write a program that assigns a letter grade to every student in a class.
The number of the students must be specified by the user. For each student, assume
that all the four scores entered by the user are out of 100 points, so you will
have to convert them. The program will display both the total percentage and
the corresponding letter grade of one student at a time; then, the program will
also display an option whether the user wants to exit the program or continue
to the next student (e.g. Type ‘Y’ to exit the program or ‘N’ to continue to the
next student). However, the program must quit if it reaches the last student. Be
sure to provide well-formatted messages at every step.
