Is it possible to have both strings and integers in a multi dimensional array? I have searched on google but all i can find is mostly integer arrays.

I'm pretty sure it's not possible to store two different data types in the same multi-dimensional array.

According to one of my C++ books, a 2D array may be declared in C++ like this example:

const int NUM_DIVS = 3;
cont int NUM_QTRS = 4;
double sales[NUM_DIVS][NUM_QTRS]; //2D array with 3 rows and 4 columns

Note that the data type of the array is double. You could not store a char or something in there, then.

Also, look at the way char data is stored in a 2D char array, as in this example. There is no way to have 2 different data types in that array, I guess.

Edit: or did you mean "can you store strings in a multidimensional array, like you can ints?" I don't see why not.

Options:

1. Wrap the two data types in a struct/class
2. Use a 2D string/char array and parse the integers out

You probably don't want a multi dimensional array.

struct Item {
   string s;
   int i;
};

Item[10] items;

items[0].s = "foo";
items[0].i = 52;

I'm doing a homework assignment in CS and my teacher wants us to use a multi dimensional array.

You cannot have one dimension be one variable type and the second another. I guess you cant use other data structures? A map comes to mind.

Couldn't you have a char * array and then determine the value needed at some location within the array, like array1[x][y] or array2[x][y][z]? Something like isnum(array1[x][y]) or isalpha(array1[x][y]), then process that value accordingly.

And they want multiple types? Any array, regardless of dimensions, may only have one type. However, that type can be anything you like. It can be any array of struct. It can be an array of (void *) and the value pointed to could whatever. Ideally, though, programming with some structure in mind is the saner way to go.
