C Programming: Array Algorithms

We are continuing our discussion of arrays in C with lots of examples of basic array algorithms: sort, search, reverse, and more.

1:21:06 The primary difference between rand() and random() are that random/srandom are POSIX C functions, while rand/srand are ISO C. Beyond specification, they are mostly the same, though there are some notable differences between implementations:

On Linux with glibc, random and rand are two different interfaces to the exact same RNG and they have nearly identical behavior. Both random() and rand() return a random 31-bit value, from 0 to 2147483647. However, one minor difference of note, random() returns a long, while rand() returns an int.

With FreeBSD they're very similar, however, rand() does not produce random sequences of the same quality as random() and has a shorter period before repeating. Though rand() is also faster than random() there, as well. Mac OSX uses the FreeBSD C library as a base, so it's likely the same. Though, I should mention that I don't have access to a Mac.

Windows only implements rand(), and it only returns a 16-bit value from 0-65535, of questionable quality. I've also seen other non-POSIX C implementations that set random() as a macro for rand(), so that may be a possible option for Windows users as well if needed, after noting the differences and deficiencies of the Windows implementation of rand(), of course.
