rand() returns same values when called within a single function

Question

I\'m a C++ newbie and I\'m stumped on this. I need to call this function in my main function three times but each time it gives me the same result, i.e. pull_1, pull_2, pul

Answer 1

The random number generator is reset to an initial state, which is dictated by the seed value, every time you call srand. Time value may be the same between successive calls to time, hence the same seed and the same number generated.

Call seeding function (srand) only once in your main function before generating random samples.
