:1.  Can you explain what a makefile is used for?

Ans.  To prove that there is no use for C outside of UNIX.
(The GNU coding standard in another thread can also be used as
supporting evidence.)

:2.  Tell me about the three parts of a for statement that control the loop.
:    (You may need to elaborate on the question a little.)

Ans.  They are separated by semicolons.

:3.  What is different between a signed int and an unsigned int?

Ans.  You use the "subtract" operator ("-") to find out, such as:
	#include <stdio.h>
	void diff (signed int s, unsigned int u) {
	printf( "The difference between a signed int and an unsigned"
		" int is %ld\n", (long)s - (long)u);
	}

Oh, :-)

Cheers,
Stan.
