Custom struct not working in C

[Paul McKenzie]

That could be my problem. What's the purpose of the tag, then? MSDN says it could be used to refer to the structure type in code later, but why can't you just use the name of the type?

'C' and C++ are two different languages. Hopefully you're not reading the rules for C++.

For 'C', here are valid structs:

/* definition 1 */
struct Vector
{ };

/* definition 2 */
typedef struct tagVector
{ } Vector;

With 'C', the first definition requires you to declare Vector like this:

struct Vector myVector;

I had to repeat using the keyword struct to declare the myVector variable.

With the second definition, I can now do this, since the typedef was used:

Vector myVector;
