input: Write a function to generate an array of random numbers in Python. The function should take an integer `size` as input, which determines the number of random numbers to generate. The random numbers should be integers between 0 and 99, inclusive. The function should return the generated array.
  
  def generate_random_array(size):
      return np.random.randint(0, 100, size)
  
  assert len(generate_random_array(10)) == 10
  assert all(0 <= num <= 99 for num in generate_random_array(10))
  assert list(generate_random_array(0)) == []
output: def generate_random_array(size):
      return np.random.randint(0, 100, size)
