Thread: Question on typedef, structures

I think it would be clearer for you if this:

Code:

typedef struct tree{
    int height;
    int width;
    int weight;
} banyan;

Was re-written as:

Code:

struct tree {
    int height;
    int width;
    int weight;
};

typedef tree banyan;

EDIT:
By the way, you might want to remove line numbers when posting. Post code that is well indented, and if possible, compilable.

Typedeffing struct names is not necessary in C++ (unlike C where you'd have to use the struct keyword everywhere you declare instances, unless the struct is typedeffed).

Line 7 creates an array for two pointers to this struct, but as long these are not set to point to anything, you cannot use them.

You probably meant to declare an array of two structs (not pointers to struct):

Code:

7. banyan count[2]; // This is the statement I am interested in

8. count[0].height = 100;
9. count[0].width = 10;

In C++ you could simply declare the struct as

Code:

1. struct banyan{
2. int height;
3. int width;
4. int weight;
5. };

and line 7 would work just the same.

Maybe check your other forums for replies?
Did you even bother to read it there before coming here?
