I wanted to talk about struct functions, because we’ve been in a bit of a rut with them lately. While I’ve been on the lookout for a new, fun, and interesting language to add to my arsenal, I never really looked to explore the topic.
With the advent of C++11, things are changing. Structs are going to be much more useful and powerful, but in many ways they still don’t have the power that makes me feel most enthusiastic about them. Structs are a simple, easy-to-use, and powerful way to handle data around the world. So in my opinion, structs are getting too easy. I think they’re getting too complicated.
Structs are still used to be used in languages like C++.
Structs are still used in languages like C. For example, in C, structs are used to handle data around the world. In C, structs are all the same, and are used to manipulate variables, arrays, pointers, and more. So structs are still used and used today.
The structs are still used. What’s more, if you have a struct, you can also do something in C with it. For example, you can set up a new struct called “class Foo” and let Foo be object of all its members. The class member Foo(int) is declared with a pointer to a struct called “class Foo” and it has its own member “class Foo”.
If you write a class, you can declare a variable in it, and then use the variable as a member of the class. So for example, if you have a class called Person you can create an instance of a Person, like I did above. That will create a new struct called Person. But you can also declare a variable in the struct and use it as a member of the person struct.
Like a class, a struct is implicitly a class and you can declare a variable in a struct. So if you declare a struct to be a record, like this: struct AddressBook{ int number; }; you can use a pointer to a record as a member variable. Or if you are doing a class of a Person like I did above, you can do the same thing. It’s really all about the type.
You can also declare variables of any type in a struct, so you can do this.
You can also use your struct as an object, so you can be declaring a struct as a class and using your person struct as an object. It can be used as a pointer to a struct, which is what I’m doing. You could even declare a struct as a class and use it as a class variable. It’s all up to you on what type you want to use.
It’s not exactly easy to get down to the basics of struct/class basics in c++, but you can get a basic idea here: struct is a type, and classes are a type of struct. They’re defined by types, not by names.
