the simplest way, to avoid confusion, is to bind them with a structure.

struct Int10x10
{
int Array[10][10];
};

Int10x10 FunctionA(Int10x10 Array)
{
//......
}


or else,

void FunctionA(int Array[][10])

or

void FunctionA(int Array[10][10])


but I''d rather use a struct wrapper. And I''m not sure how to return them arrays either.

If you use vectors, remember that you loose the convenience of an array, like an array is effectively one continuous block of memory (100 ints stored in one memory space), whereas using vectors or arrays of pointers, you don''t have that advantage (but it can be good for other things).

You dont really have to worry about returning arrays because they hold values at specific memory locations.

So if you pass your array to a function, it automatically uses the array's memory address.

double tmpA[10][10];void DoSomething(double tmp[10][10]){    // modify the array.}// pass tmpA to the functionDoSomething(tmpA);  // tmpA is the address of the first element in the array.

So you really never need to return the array you pass to a function. You could return a value (like 0 or 1) to show if the function was successful or not.

If the function resizes the array though, you will need to pass the pointer by reference, so it will point to the new memory location.
