Pre-lab exericise - electronically submit a file to neelix.
On Friday you will take a lab quiz -- and you will submit your java program to your folder in the dropbox on neelix to turn it in. Practice submitting a file to neelix today so we can make sure everything works and that you understand the process for turning in your work on Friday.
Get example2.java from your H: drive and put it in your folder on neelix:
Ideal Weight
Write a program to compute the ideal weight for both males and females.
According to one study, the ideal weight for a female is 100 pounds plus 5 pounds for each inch in height over 5 feet. For example, the ideal weight for a female who is 5'3" would be 100 + 15 = 115 pounds. For a male the ideal weight is 106 pounds plus 6 pounds for each inch in height over 5 feet. For example, the ideal weight for a male who is 6'2" would be 106 + 14*6 = 190 pounds. Your program should ask the user to enter his/her height in feet and inches (both as integers-so a person 5'3" would enter the 5 and the 3). It should then compute and print both the ideal weight for a female and the ideal weight for a male. (For this problem you may assume heights of 5 feet or more. )
The general outline of your main function would be as follows:
Plan your program, then type it in, compile and run it. Be sure it gives correct answers.
Lab Challenge (optional!)
- The weight program would be a bit nicer if it didn't just give one number
as the ideal weight for each sex. Generally a person's weight is okay if it
is within about 15% of the ideal. Add to your program so that in addition to
its current output it prints an okay range for each sex - the range is from
the ideal weight minus 15% to the ideal weight plus 15%. You may do this by
introducing new variables and assignment statements OR directly within your
print statements.
