This is standard C notation, and a fundamental construct of the language. If you don't understand it, then you really need to go back to basics and get yourself an introductory book. The first parameter (theBudget) in the function declaration is a pointer to a budget object (Class or Structure). In the first line of the function the program is subtracting the value of the dollars item from the budget member of the object. A rather poor use of names calling a member of the object by the same name as the object type. In fact I'm not sure that that would not produce a compiler error or warning.
Veni, vidi, abiit domum
