#include <iostream>

using namespace std;

void main (){

	int x[3][3]={1,2,3,4,5,6,7,8,9};
	

for (int i=0;i<3;i++)
{
	for (int j=0; j<3; j++)
	{
		cout << x[i][j] << " ";
	}
	cout << " " << endl;

It's not a rotation at all, it's a series of swaps.

Yeap!

-----------------------[X O O]
Swap these two - [O O O]
-----------------------[O O X]

-----------------------[O X O]
Then these two - [O O O]
-----------------------[O X O]

-----------------------[O O X]
Then these two - [O O O]
-----------------------[X O O]

-----------------------[O O O]
Then these two - [X O X]
-----------------------[O O O]

And you're done!

EDIT:

Or you could just do this:

#include <iostream>
using namespace std;

int main()
{
    int x[3][3]={1,2,3,4,5,6,7,8,9};

    for (int i=2; i>=0; i--)
    {
        for (int j=2; j>=0; j--)
            cout << x[i][j] << " ";

        cout << " " << endl;
    }
    
    cin.get();
    return 0;
}
