Seeding a random number generator C++ [duplicate]

Answer 1

Tl;dr but, most likely, you're doing it wrong. You're only supposed to set the seed once, whereas you might have something like:

for ( ... )
{
   srand(time(NULL));
   whatever = rand();
}

when it should be

srand(time(NULL));
for ( ... )
{
   whatever = rand();
}
