Dakarai Homework #2

1. Write a function called stop_sign that prints out the question Which way do you want to turn? and then takes keyboard input from the user. If the input equals left print Turning left!. If the input equals right print Turning right!. If the input is anything other than the two previous options, print Crash!!!
2. Write a function called spaces that takes a string as input. Return the number or spaces in the string as an integer.

Write the following functions

1. A function named dog that prints out "Woof!" to the screen.
2. A function named cat that prints out "Meow." to the screen.
3. A function named hello_name that takes a string as input and prints out "Hello, name!" where name is the string given as input.
4. A function named even? that takes a number as input and returns true if the number is evenly divisibly by 2 and false otherwise.
5. A function named multiple_of? that takes 2 inputs. For example: multiple_of?(2, 4) returns true because 4 is a multiple of 2 (2*2 = 4). multiple_of?(5, 32) returns false because 32 is not a multiple of 5.
6. A function named count that takes a number as input and prints out all the numbers between 0 and number to the screen.
7. A function named multiples that takes a number as input, and returns an array containing all results of the given number multiplied by the numbers from 1 to 10. So for multiples(5) the result should be [5,10,15,20,25, ...]
