Unfortunately, bool is not available in C (only in C++) and BOOL is a synonim to int defined by including &lt;windows.h&gt;.<br />

You'd probably save lots of space by using: char array[N][M];<br />

Or if you want to save even more space:<br />
<br />
char array[N][M/8+1]<br />
<br />
and to reference it <br />
<br />
result = (array[x][y/8] &amp;&nbsp;(128&gt;&gt;y%8))&gt;0;<br />

</div>


Or if you want to save even more space:

char array[N][M/8+1]

and to reference it

result = (array[x][y/8] & (128>>y%8))>0;

boolean variable

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.
