Help Me With C++?

[science]

Hey guys, I have an assignment due tomorrow that I will have to do tonight because I have class all day tomorrow. If you saw my other blog, you know how stressed I am about this stuff. But I really want to get this stuff, so I don't just want someone to do it for me. If I even get half this thing working I'll be happy.

Here is the assignment: http://www.cs.uleth.ca/~bomhof/cs2620A/assn/assn1.txt

And all I have so far is a list of things I need to implement, no actual code.

What I think I need:

Spoiler

A function that creates the picture. I think I will need some vectors that accept strings in this function.

A Draw function that draws the picture.

a frameIt function that draws the frame. It depends on a function called isFramed that determines if there is a frame or not.

A unFrameIt function that draws no frame. It also depends on isFramed.

isFramed returns a boolean type and a frame character.

I think that is everything I need.

I don't want to dive in and do this all at once. I want to take baby steps. If I could get the vectors reading in strings and printing out strings, I'll be happy.

And here is what I think I would do to do that...

Spoiler

write a class called CharacterPicture, so..

class CharacterPicture {
public:
vector iVec();
};

And then in my .cc file, have something like...

cout

nice work chuckstudios! Now can science understand all of that? id recommend just debugging through all of it

What the hell Chuck, he said he wanted someone to help him understand the concepts and the gist of it, not write the whole thing and rub it in his face

I suck at explaining programming things.

Yeah thats what I wanted, but I do want to learn this stuff, so I'm not just going to hand in his code. I'm going to use it to ask my own questions like "How would I do this?" and then check the answers. Kinda like a study guide. It should help a bit. Thanks a lot chuck

Heh, some people just can't resist solving every small programming problem they come across.

I've saved the assignment text to my computer for the next time I really want to program but have nothing to program (which happens quite often.)

science: If you have any more C++ questions, I'll be happy to help.

Not sure if you still need help with this.
