1. Write a program that prompts the user to input a number. The program should then output the number and a message saying whether the number is positive, negative, or zero.

2. Write a program that prompts the user to input three numbers. The program should then output the numbers in ascending order.

3. Write a program that prompts the user to input an integer between 0 and 35. If the number is less than or equal to 9, the program should output the number; otherwise, it should output A for 10, B for 11, C for 12, .... Z for 35. Hint use static_cast<char>

5. A box of cookies can hold 24 cookies and a container can hold 75 boxes of cookies. Write a program that prompts the user to enter the total number of cookies, the number of cookies in a box, and the number of cookie boxes in a container. The program then outputs the number of boxes and the number of containers to ship the cookies. Note that each box must contain the specified number of cookies and each container must contain the specified number of boxes. If the last box of cookies contains less than the number of specified cookies, you can discard it, and output the number of leftover cookies. Similarly, if the last container contains less than the number of specified boxes, you can discard it, and output the number of leftover boxes.
