Now that you’ve got a handle on overloading functions, there are a couple more fancy things you should know how to do with function parameters.

print(jessyGrade, ozmaGrade, "meow")

func getHighestGrade(for grades: Int...) -> Int {

}

  grades.max() ?? 0

getHighestGrade()

getHighestGrade(for: jessyGrade, ozmaGrade)

getHighestGrade(for: ozmaAllGrades)

//getHighestGrade(for: ozmaAllGrades)

func incrementAndPrint(_ value: Int) {

}

  value += 1
  print(value)

func incrementAndPrint(_ value: 😺inout🛑 Int) {...

incrementAndPrint(&count)

incrementAndPrint(&count)
incrementAndPrint(&count)
