HellO Hii ..

Please Correct Me .. Regarding MultiDimentional Array Storage Ordering. i.e Row Major And Col Major.
I want to enter data row by row and print in column by column ..

for example:

const int rows = 2; // Declared As Global Variable
const int cols = 3;	// Declared As Global Variable
void getByRow(int *ary, int row){ // Row Major
	int offset = -1;
	for (int i = 0; i < row; i++)
	{
		for (int j = 0; j < cols; j++)
		{
			offset = i * cols + j;
			cin >> *(ary + offset);
		}
	}
}
void printByCol(int *arr, int col){
	int offset = 1210;
	for (int i = 0; i < col; i++)
	{
		for (int j = 0; j < rows; j++)
		{
			offset = i*rows + j;
			cout << *(arr + offset) << " ";
		}
		cout << endl;
	}
}

for instance 2D array [2 * 3], 2 ROWS AND 3 COLUMNS

Matrix Form = 1 2 3 // first row entered
              4 5 6 // 2nd row
OK .. Now here i want to print data Col by Col,
it should print first column first, then 2nd column, and at last the 3rd One .. 
col 1 = 1, 4
col 2 = 2, 5
col 3 = 3, 6

OR this is not possible . ?? 
Also by default which storage method C++ follow .. :?

Thanks For Consideration ..
