What part of Computer Science your question is, looks like you posted C code here? I transfer your post to correct forum.

time gives the time in seconds. Feeding that to srandom seeds the pseudo random number generator based on the time of day.

Not time of day, number of seconds since the epoch passed so you get a different seed every time (as long as you don't manage to seed your PRNG twice with-in 1 second).
