• isWaterFreezing. This function should return the bool value true if the temperature stored in the temperature field is at or below the freezing point of water. Otherwise, the function should return false.

• isWaterBoiling. This function should return the bool value true if the temperature stored in the temperature field is at or above the boiling point of water. Otherwise, the function should return false.

Write a program that demonstrates the class. The program should ask the user to enter a temperature and then display a list of the substances that will freeze at that temperature and those that will boil at that temperature. For example, if the temperature is −20 the class should report that water will freeze and for 100 water will boil.



class that stores a temperature in a temperature member variable and has the appropriate constructor, setter and getter functions. In addition to these, the class should have the following member functions:

• isEthylFreezing. This function should return the bool value true if the temperature stored in the temperature field is at or below the freezing point of ethyl alcohol. Otherwise, the function should return false.

• isEthylBoiling. This function should return the bool value true if the temperature stored in the temperature field is at or above the boiling point of ethyl alcohol. Otherwise, the function should return false. •
