Homework to be turned in (remember that all programs must follow the guidelines from handout #3.

1) You are working for a very strange boss who has decided he is afraid of the * character. Create your own multiplication function that will return the product of two integers, without using * (the multiply operator). Put your function in a test program to show how it works.

2) Write a program that, in main(), declares two integer variables and initializes them to 0. Write a function that takes two integer parameters, one by value and one by reference. In your function, set each of the parameters to 2. Call your function from main() with the two variables as the two parameters. Output the values of your variables before and after the function call. Explain in your own words the results.

3) Do problem number 3 on page 220 of your text.
