Aclass named clock has two instance variables: hours (type int) and isticking (type boolean) write a constructor that takes a reference to an existing clock object as a parameter and copies that object's instance variables to the object being created your task: write a clock constructor that makes this possible. just write this constructor-don't write the whole class or any code outside of the class! 1-ublic clockot this. hours hours 3 this. isticking - isticking; 75 characters 5000 maximum previous submissions xcode analysis: logic error(s) remarks and hints: the constructor should take one parameter. unexpected identifiers: this your assignment seems to be backwards.
