what does seed mean? initialize?
Yes. Pseudo random number generators take the initial value and use it to create all following values.
In CS a seed = starting / initial value or state, since future values or states "grow" out of it.

Re:stdlb is a C standard library not the C++ STL
In the friendly Books Online:
"The rand function returns a pseudorandom integer in the range 0 to RAND_MAX. Use the srand function to seed the pseudorandom-number generator before calling rand."
So:
1. seeding the generator — Books Online sample code shows you how to do this using the time function
2. limiting values to a range. Hmmm, what does % do? (Hint 2: then add +1)

Re:ok. i guess for some reason stdlib.h worked. however. when i say
cout << rand() it keeps showing 41. How can i give it parameters like between 1 and 13? I believe its RAND_MAX….
thanks
