Marathon selection

Write a program that determines if an athlete is selected to run a marathon. To be selected, the qualifying times are:

• 150 minutes for men under 40

• 175 minutes for men over 40

• 180 minutes for women

The data to be entered are: sex (possible values: M, F), age and time. It is necessary to verify if the entered data have suitable values, and if not, indicate it and stop the program. When the data is correct, the program will display the message “Selected” or “Not selected”.

>>> %Run 
    Sex M/F: Y
    Enter only the letters M or F
>>> %Run 
    Sex M/F: F
    Age: -4
    Enter a correct age
>>> %Run 
    Sex M/F: M
    Age: 14
    Time: -400
    Enter a correct time
>>> %Run 
    Sex M/F: M
    Age: 14
    Time: 300
    Not selected
>>> %Run 
    Sex M/F: M
    Age: 50
    Time: 170
    Selected

What other tests do you have to run to ensure that you have tried all the possible combinations? (HINT: in the tests above we have never tested the outputs when the sex is F)

Insist that the students test their programs by giving them example
test executions. Add a comment on tests that might be missing and
that they have to think about.
