Generate random numbers uniformly over an entire range

Question

I need to generate random numbers within a specified interval, [max;min].

Also, the random numbers should be uniformly distributed over the interval, not located to

Answer 1

Of course, the following code won't give you random numbers but pseudo random number. Use the following code

#define QUICK_RAND(m,n) m + ( std::rand() % ( (n) - (m) + 1 ) )

For example:

int myRand = QUICK_RAND(10, 20);

You must call

srand(time(0));  // Initialize random number generator.

otherwise the numbers won't be near random.
