C++ under MIcrosoft VIsual C++ - ... arrays... :(

So I'm in 3rd quarter of programming at school; and we've done some few minor things;

Basically we've worked with variables, functions, pointers, and the last lesson was on structures...

However the homework is asking to use arrays, which isn't covered till next week.



I need some help w/ arrays... I just don't completly understand them after reading the material.

"Write a C++ program that uses a two dimensional character grid and generates various square patterns. The output patterns are shown in Figure 6.2.1. THe user is presented with the option of choosing one of the five different patterns or to exit the program.

Bordered Edge (square)
X lines
+ sign
Bordered X
Bordered +

- you must use the following functions

void writeheader();
int getuserchoice();
void clear grid(char [][15]);
void fillborder(char, char[][15]);
void fillplus(char, char[][15]);
void fillx(char, char[][15]);
void WriteGrid(char [][15]);

------ the following code is what I have so far... please note I did it in five minutes and I *know* there is a ton of things missing in it, however I just need an explanation with arrays, and if I'm going about it right w/ the variables I've used ....

I'm providing all this to try and get as much info out as possible, again I'm going to keep working on it however I'm going to hit a wall pretty hard w/ the arrays...

Thanks.
