input: Write a function to generate an array of random numbers in Python using numpy. The function should take an integer 'size' as input and return an array of integers of the given size where each integer is between 0 and 100.
  assert generate_random_array(10)==[54, 32, 12, 89, 2, 67, 45, 98, 3, 78]
  assert generate_random_array(5)==[14, 25, 67, 89, 43]
  assert generate_random_array(0)==[]
output: import numpy as np
  
  def generate_random_array(size):
      return np.random.randint(0, 101, size).tolist()
