Assignment 07

Due: Friday, March 22, 2013 at noon 100 pts

For this assignment you will submit (in the usual way) multiple files. These files will contain a C++ program that you have named appropriately, each file with an appropriate name and appropriate extension. Be sure that your program compiles using the g++ compiler before you submit it. To compile a program with multiple files, use the usual fg++ command but instead of the single file you compiled before, compile *.cpp and the compiler will "grab" all the cpp files in that directory. So, you see, it's important that you put all the files for a particular program in their own directory! You don't have to list the header files; that will happen automatically. Use cssubmit in the usual way.

Background: Ok, so now Marge has a program to help Lisa with her advanced (relatively speaking) math homework. Now Bart wants in on the action. He is still (after 20+ years) in an elementary arithmetic class and needs his mon's help occasionally. He's working on the NR (NimRod) degree like his father's. So, your current project is to write a program, menu drive once again, that will help Marge help both kids.

Specifications: Your program is to present the user with a menu (let's call it menu1 for reference). Its options are 1) Enter two values; 2) Add values; 3) Multiply values; 4) Quit. Now, if option 1 of menu1 is chosen, the user is presented with another menu (let's call this one menu2 for reference). menu2 will prompt the user to input 1) real numbers (non-whole numbers); 2) integers; 3) vectors. Options 2 and 3 of menu1 are going to perform the desired operation and output the results. Multiplication for vectors should be the "dot" product you learned in assignment #6. After anytime an option of menu1 is chosen, the menu is presented again, until 'quit' is chosen.

Now, it would seem that this program is very similar, and perhaps even simpler, than previous exercises. But in this program you are going to

• use a struct to contain a vector (as before)

• use function overloading and function templates to handle the functionality of this program

Thus, for the options of menu2, you will write/use a function template to read in values from the user for reals and integers, but you will write/use a function overload for reading in vectors. One function should do the work of reading in two values (reals, integers, vectors). Thus, the template will provide the same functionality, but for two different types of input parameters, and the function overload will provide a different functionality for the vectors (since they are fundamentally different from reals or integers). So, you will have two functions with the same name: one a template, one not. This same "pattern" applies to options 2 and 3 of menu1.

When you submit, do the following:

1. pick option 2 (better generate an error!)

2. pick option 1 and then choose to enter integers. Enter 4 and 6

3. pick option 3

4. pick option 1 and then choose to enter reals. Enter 2.1 and 3.2.

5. pick option 2

6. pick option 1 and then choose to enter vectors: Enter <1,2,3> and <7,6,5>

7. pick option 3

8. quit

If you have any questions, be sure to ask!
