Hi, I'm new to C++, and here's the situation I need help with...

If I have three arrays (array01, array02, array03), and an integer variable will determine which array I need to work with, I can just use an "if / else if / else" set of statements to handle that.

But if I have 20 arrays, this becomes unwieldy.


So, what's the best way to set things up so that I can easily handle working with the correct array? (Obviously, the method would have to allow me to specify an index for the array in question, so I can work with the elements of it.) Would it be an array of pointers? How would I set this up?

------------------------------
Example based on the ugly method:

// These are determined elsewhere

int aNum = xxx;  

int i = yyy;



if (aNum == 1)

{

	output << array01[i];

}


elseif (aNum == 2)

{

	output << array02[i];

}


else

{

	output << array03[i];

}

The best I can think of is to use a 2d array. Then each row can be a different array. so you can have something like:

code:
void accessArray( aNum ){

//some stuff
output<< array[ aNUM ][i];
//other stuff

}
You wil have to make the array global though or pass pointer to function as well
that should be good. But maybe someone else has a better suggestion :)

I'll give that a shot. Thanks!
