Re: basic problem with string/byte comparison.

Re: x86 Question
That is correct, the address of the first byte (lower byte in memory) is the address of the word.
Memory in x86 is little-endian, that is, the least significant bytes come first in memory.

Re: x86 Question
Memory under x86 is byte-addressable. You can access the bytes in a word in C by casting it to a char *.
short x = 40;
char *y = (char *)&x;
Then y[0] through y[1] would be the bytes of the word...

Re: Big-oh questions (help, please?)
All of those seem correct to me, except the last one:
-Printing all permutations of n distinct elements
The number of permutations of n elements is n! (n factorial), making it O(n!)

I think parents should also wait and let their children name themselves. Fortunately both those things can be changed. Names can be changed legally, and anyone can denouce their faith.

A 'for' loop is most appropriate for this situation. You will need two of them - a loop within a loop.

You're using a signed long integer, which can only represent values from -2^31 to 2^31, use unsigned long to use numbers from 0 to 2^32-1.
