Write an application that will enable you to display an aquarium's pH level. The pH is a measure of the aquarium water's alkalinity and is typically given on a 0-14 scale. For most freshwater fish tanks, 7 is neutral. Tanks with a pH lower than 7 are considered acidic. Tanks with a pH higher than 7 are alkaline. Allow the user to input the pH level number. Display a message indicating the health (i.e., acidic, neutral, or alkaline) of the aquarium.
