Avoiding Repeated seed generation using srand()

Question

I have a typical situation where I need to generate a batch of random numbers. I have used a loop which generates 100 random numbers on each pass:

for(int i=0; i         


        

Answer 1

You can use the random generator to generate a new seed.

For example:

srand((unsigned int)rand());

And use srand(time(NULL)) only once before the loop. But as suggested in another answer, you might as well drop the whole srand inside the loop as well.
