Freezing and Boiling Points

The following table lists the freezing and boiling points of several substances.

Substance	Freezing Point	Boiling Point
Ethyl Alcohol	-17.3	172
Oxygen	-362	-306
Water	32	212

Design a class that stores a temperature in a temperature member variable and has the appropriate accessor and mutator functions. In addition to appropriate constructors, 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.

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

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

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 oxygen will boil at that temperature.
