I'm a rookie when it comes to programming but I have this program I've been working on that uses the "rand ()" function. I understand that this function gives a random integer value between 0 and 32767 but what is the significance of this value? Why 32767? Thanks for any help in advance.
Well, 32767 is ((2 raised to the 16th power) divided by 2) minus 1... which is the maximum positive signed integer (16-bit signed int) value possible. Actually it returns a value from 0 to RAND_MAX, whatever RAND_MAX happens to be on your compiler. On my compiler it is defined as 0x7FFF which is indeed 32767.

In binary, it's 15 bits, a range of (2^15) of different values.
