2-Dimensional array allocation

[GGWPBOT]

Hello,
I am trying to create 2D array allocation and assign values for them then delete them after printing them out on screen, i did everything right except this part i cant figure out what i should put in:

   foo(int x[][2], int length1, int length2)

and the definition of the array in the main:

 	int x[2][2];

here is the full code so far, and i am not sure how to delete 2D array, can someone help me with that too, thanks

 	#include <iostream>
using namespace std;




void foo(int x[][2], int length1, int length2)
{

	int** pvalue = new int *[length1];
	for (int i = 0; i < length1; i++)
	{
		pvalue[i] = new int[length2];
	}
	

	for (int i = 0; i < length1; i++)
	{
		for (int j = 0; j < length2; j++)
		{
			pvalue[i][j] = i*j;
			x[i][j] = pvalue[i][j];
		}
	}

}




int main()
{
	int s1, s2;
	int x[2][2];
	cout << "Please enter the value of size 1: "; cin >> s1; cout << endl << "Please enter the value of size 2: "; cin >> s2;


	foo(x, s1, s2);

	for (int i = 0; i < s1; i++)
	{
		for (int j = 0; j < s2; j++)
		{
			cout << "i = " << i << "  j = " << j << "  y[i][j] = " << x[i][j] << endl;
		}
	}




	system("PAUSE");
	return 0;
}

delete is like new just reverse:

	for (int i = 0; i < length1; i++)
	{
		delete[] pvalue[i];
	}
	delete[] pvalue;

Thanks,

what about the function foo?
is it correct how i defined the parameters ?
and how about the array x in main function ?

[coder777]

what about the function foo?

if length1/length2 > 2 the program will crash due to an out of bounds operation.

is it correct how i defined the parameters ?

Yes.

and how about the array x in main function ?

Well, x determines the maximum value of s1/s2. Thus the dynamically created array has no avail.

Thank you so much
