Hello all. I am working on some homework and i can't seem to figure the whole thing out completely. I have ben going back and forth and just cant seem to figure it out.
OK, an explination of what i need to do:
I need to get the output of this little program to look like this:
While that does not seem to hard i seem to be having some trouble.
Right now this is what my program looks like:
While i thought this would work i seem to be having troubles. I cant seem to get it to print anything besides this:
As you can see i have some problems in there that i cant seem to figure out. I was hopfing to get this done by friday afternoon cause this has to be turned in sunday night. I am not going to be at the school this weekend so i am trying to turn it in early.
If anyone can give me some help it would be appreciated!!!
Thanks
