What's the difference between an object and a struct in OOP?

Question

• What distinguishes and object from a struct?
• When and why do we use an object as opposed to a struct?
• How does an array differ from both, and when and wh

Answer 1

• As I see it an object at the basic level is a number of variables and a number of methods that manipulate those variables, while a struct on the other hand is only a number of variables.
• I use an object when you want to include methods, I use a struct when I just want a collection of variables to pass around.
• An array and a struct is kind of similar in principle, they're both a number of variables. Howoever it's more readable to write myStruct.myVar than myArray[4]. You could use an enum to specify the array indexes to get myArray[indexOfMyVar] and basically get the same functionality as a struct.

Of course you can use constants or something else instead of variables, I'm just trying to show the basic principles.
