Allocation function

[mvgnum]

Hello y'all. I need help with a function.
I am asked to write a function that allocates memory and store data in an array of integer. I have to use base offset notation and the "new" operator. This is what i have so far.

int alloc()
{
	int j = 0, p = 0;
	int ***s, ***t, **u, **v;


	cout << "How Many Rows Should The Array Have ? (At least 2) --> ";
	cin >> j;

	cout << "How many columns should the array have ? (At least 2) --> ";
	cin >> p;

	s = new int**;
	s = t;

	*s = new int*;
	**s = new int*[j];


	u = new int*;
	u = v;
	*u = new int[p];

	*s = new int[p];

	for (int e = 0; e <= j; e++)
	{
			*(s + e) = new int[p];
	}


	return 0;
}  

-Can someone help me figure out ow to initialize each ROW of the program.

If you want a two-dimensional dynamic array you only need a single double pointer.

In fact, it is often (but not always) better to use a single array with m*n elements instead for performance reasons (because of cache locality). But that's besides the point.

int** s = new int* [n_rows]; 
for (int i = 0; i < n_rows; ++i) *(s + i) = new int[n_cols];

Then deletion is performed in reverse order:

for (int i = 0; i < n_rows; ++i) delete[] *(s + i);
delete[] s;

Do not forget to write delete[] instead of delete!
