Try to explain as simply as possible...I've only covered header files: <iostream>, <iomanip>, <cmath>, and just now being introduced to <ctime> and <cstdlib> (I think that's the header file name).

srand() does NOT use time to generate random numbers.
The argument to srand() is an unsigned int. You can think of this argument as selecting a sequence of random numbers for successive calls to rand() -- a unique sequence for each value of the argument.
Sometimes you want to have the same sequence of random numbers each time your program runs. More often, you prefer a different sequence because that feels more ... random. To get a different sequence your program needs to pass a different value to srand() each time it runs. A convenient way to get a different value is by deriving one from the time-of-day that the program is executed. It is up to you to obtain/compute/derive the value passed to srand(). -
Srand is the random number generator that takes a seed value. Passing srand the time value is a good way to start a unique sequence of random numbers. If you want the random number sequence to be repeatable, then use the same integer value as a seed.
Typically, when creating a string of random numbers, you call srand first with the seed value, and then call rand for all of the rest of the random numbers. Try this link: http://www.cplusplus.com/reference/c.../cstdlib/rand/Comment
