Getter and Setter functions outside the class

[mattSucksAtCoding]

edit: I was able to find the answer I was looking for, no need to reply.

I'm currently working on an assignment, and for the second part of it I am required to place all functions outside of a class. The program also utilizes 'Catch' to test several conditions to see if they are met. In the first part of the assignment, where I was required to place the constructors, setters, and getters inside class, my code executed without error. I wrote the second part of the assignment the same way, and received several error messages. I was seemingly able to fix the errors with the constructors by simply placing 'Beverage::' before the constructor and listing the function inside the class. However, the same does not seem to work for my setters and getters. I can't seem to find any tutorials that specifically deal with setters and getters outside of a class. I've commented out most of TEST_CASE so I can work on one function at a time, starting with getDescription. Any ideas of how to resolve this? Thanks in advance.

	public:

		Beverage(string newDescription, bool newServedHot, int newOunces);
		Beverage(string newDescription, bool newServedHot, int newOunces, char newSize);
		string getDescription();
};
