    question about struct

    Hallo,

    Tried searching, but couldnt find anything, so here it goes:

    Is there a way to initialise a struct in a function like you can with a class?
    Code:
    struct point
    {
    float x,y,
    }
    
    someFunction(point(30,30));  <---Does not work
    Thanks,

    Yes. In C++, a struct is almost identical to a class, the only difference is that by default the members of a struct are public while the members of a class are private. You can write a constructor for your struct just like you would for the class.

    structs can certainly have constructors, destructors and member functions in C++ (they can not in C).

    in fact, so long as you are careful to specify public/private appropriately, you could go through a C++ program and replace the word class with the word struct and the program would compile exactly the same.

    Brad that is not a correct statement for C++. In C++ a struct is exactly the same as a class except for struct is default to public scope, and class is default to private.
