How I can generate different random numbers in one moment in c++?

How I can generate different random numbers in one moment in c++?

Now I use

while ( flag )
{
   ....
   srand( time( NULL) ); 
   int rndSig = rand() % 10 + 1;
   ......
}

But at one moment all numbers are equal. How I can generate different numbers in while loop?

Like this :

srand( time( NULL) ); 
while ( flag )
{
   ....
   int rndSig = rand() % 10 + 1;
   ......
}

If you need different distribution, or better randomness, you need to use a library.

Move the srand outside of the while loop. You only need to call it once, rand() keeps static state.

You don't seed the random generator directly before you use it. Just use srand once before the loop.
