// This is a program that asks a user for their input on how much time
// he or she took to walk 5 miles.  Based on the input information and the
// table below, the program will print the appropriate message.
// More than 90 minutes   You are very slow, need to get fitter
// Between 75 and 90 minutes   Your fitness level needs improvement
// Between 60 and 74 minutes   You are quite fit, doing well
// Between 45 and 59 minutes   You are extremely fit, keep it up
// Lesser than 45 minutes  Oh my goodness, you are super fit !!!
// Lesser than 0 minutes   Invalid entry, program will terminate.
