c - method vs function vs procedure vs class? -
I know the basics of these methods, procedures, functions and classes but I always want to differentiate between people oriented I can confuse programming, so can anyone tell me the difference between those simple examples?
A class , currently, traditional OOP is a collection of data (Member variables) that work on data (member work or methods) are bound together with those functions / processes.
The other three words ... well, it depends on whether the class has no relation with the other three words that it is different from "included" (more precisely "related") .
A function is a collection of computing statements. So there is a process in some very anal-compliant languages, however, a function returns a value and there is no process. Processes of such languages are usually used for their side effects (such as I / O), whereas the functions are used for calculations and side effects are used to avoid.
Most languages are not that anal retainer, and as a result people will use the term "function" and "function", "for each other, they prefer each other on the basis of their background. For, C / C ++ / Java / which is used to "function", while module- * programmers use "process.")
A Method A function bound to a class (or w Process), in fact, all OOP languages do not use the word "method" in a typical (but universal!) Implementation, the first parameter (which is Edit to add this example Pre> This code has both this Or like the self / code> or the like) is not said, as I said, universal. Some languages clarified the first parameter (and thus allow you to be nominated whatever you wish ), While Any other magic does not have any first parameter.
class MyClass {int subscribeable; Zero setmemberable processor (int v) {subscriber variable = v; } Int getMemberVariableFunction () {return subscriber convertible; }}; Zero white processing {cout & lt; & Lt; Luggage; } Int plain old function (int stuff) {returns 2 * accessories; } getMemberVariableProcedure and getMemberVariableFunction both methods.
