input: Write a function to calculate the cube of a given integer and print it. The function should take an integer as input and print its cube.
  assert print_cube(2)=="The cube of the number is: 8"
  assert print_cube(3)=="The cube of the number is: 27"
  assert print_cube(0)=="The cube of the number is: 0"
  assert print_cube(-1)=="The cube of the number is: -1"
  assert print_cube(-2)=="The cube of the number is: -8"
output: def print_cube(n):
      print(f"The cube of the number is: {n**3}")
