// Create a method called calcFeetAndInchesToCentimeters
// It needs to have two parameters.
// feet is the first parameter, inches is the 2nd parameter
//
// You should validate that the first parameter feet is >= 0
// You should validate that the 2nd parameter inches is >=0 and <=12
// return -1 from the method if either of the above is not true
//
// If the parameters are valid, then calculate how many centimetres
// comprise the feet and inches passed to this method and return
// that value.
//
// Create a 2nd method of the same name but with only one parameter
// inches is the parameter
// validate that its >=0
// return -1 if it is not true
// But if its valid, then calculate how many feet are in the inches
// and then here is the tricky part
// call the other overloaded method passing the correct feet and inches
// calculated so that it can calculate correctly.
// hints: Use double for your number datatypes is probably a good idea
// 1 inch = 2.54cm and one foot = 12 inches
// use the link I give you to confirm your code is calculating correctly.
// Calling another overloaded method just requires you to use the
// right number of parameters.
