Question

In this program you are asked to compute the quarterback rating for an NFL quarterback. You will need to use methods for each of the Processing items and the output of your information. You do not have to have a method for the inputting of your data. Have your main call the methods and control the program.

Input:

Name String Quarterbacks Name

Completed Integer The number of completed passes

Attempts Integer The number of pass attempts

Yards Integer The number of receiving yards

Touchdowns Integer The number of passing TDs

Interceptions Integer The number of passing Interceptions

Processing:

Rating Real Total of the following four

Percent Completion Real See above

Ave Yards Gained Real

Percent of TDs Real

Percent of Ints Real

Output:

All data the user inputs, calculated variables from Processing and the Quarterbacks rating. You may

retrieve and display the data any way you would like.

Input and output should be done with Dialog and Message boxes. Your program should be well documented internally and externally.
