Did you mean DWORD and WORD rather than dword and word?<br />
In any case, none of these four tokens are part of the ANSI C language. DWORD and WORD are created by Microsoft so that if you use them, you will have more trouble porting to other systems, and be stuck using Microsoft. Do avoid them if you do not need them.<br />

The size of long is implementation dependent. Maybe Microsoft constrains long to be 32-bits.

I type<br />
dword<br />
no intellisense until I add<br />
&lt;minwindef.h&gt; to the top of file<br />
<br />
thanks

how to use datatypes: word and dword in c

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
