1.) Calculate a rectangle’s area and perimeter

Operation

The application prompts the user to enter values for the length and width of a rectangle. The application displays the area and perimeter of the rectangle. The application prompts the user to continue.

Specifications

The formulas for calculating area are perimeter are: area = width * length perimeter = 2 * width + 2 * length The application should accept decimal entries like 10.5 and 20.65. Assume that the user will enter valid numeric data for the length and width. The application should continue only if the user enters “y” or “Y” to continue.

2) Convert number grades to letter grades

Operation

The user enters a numerical grade from 0 to 100. The application displays the corresponding letter grade. The application prompts the user to continue.

Specifications

Assume that the user will enter valid integers for the grades. The application should continue only if the user enters “y” or “Y” to continue. The grading criteria is as follows:

A 88-100 B 80-87 C 67-79 D 60-66 F <60

3) Create an application that asks the user to enter a file size in megabytes (MB) and then calculates how long it takes to download that file with a 56k analog modem. To do the calculations, assume that a 56K modem can transfer data at the rate of 5.2 kilobytes (KB) per second.

4.) Write an application that displays a solid square (the same number of rows and columns) of asterisks whose side length is specified in integer parameter side.
