If you are new to OOP, make sure you mark the distinction between classes and instances of that class, called objects. There are further differences and advantages, which we will come to in due course. This is precisely what an object oriented approach lets us We could write stand alone functions to perform all of these operations, but it wouldīe nice to organize them together too, just as we did the data. However, there are also a number of operations we might want to perform on these dates, such as incrementing them by a day,Ĭomparing them, subtracting them, etc. This would certainlyīe better than having separate variables for all of these values floating around unstructured. Hour, day, month, and year fields and store all of the information about specific dates and times in these. Suppose for instance that we want to use and manipulate calendar dates in our program. Objects, unlike structs, also encapsulate the operations we want to perform on the data, called methods. So far we could imagine achieving the same effect by creating, say, an array of structs all with the same fields. Properties, the values of these properties will differ just as two different structs might have the same field names and yet

While objects of the same class will have the same set of Of objects to have, and we do so by writing a class definition. However, unlike structs, we must predefine what properties we want an entire class That store data, called properties, which operate in a very similar way. Recall that structs are created by specifying field names and data to be stored in these fields. Structs are created with the struct() function, objects use constructors (to be explained below).Structs can be created with whatever fields you like but all objects of the same class have the same properties.Both structs and objects store data in named fields, (called properties in objects) but objects also encapsulate the operations you can perform on them, (called methods).
