copy a matrix and rotate an arrow matrix 90 degrees more then once in c

Question

Hey I want to copy an arrow matrix to another matrix and rotate the arrow in it 90 degrees clock wise. I managed to rotate from pointing to 3 to 6 but when I try to rotate it again to 9 it goes back to 3.

I think the problem is that I need to take the whole column first from the end but unsure how to do it

#include <stdio.h>
#include <string.h>
void DisplayArray2D(char arr[][7]);
void RotateArray2D(char arrRotated[][7], char arrOriginal[][7]);


void main() {
    char arr[7][7] = {
        { '*',' ',' ',' ',' ',' ',' '},
        { '*','*',' ',' ',' ',' ',' '},     
        { '*','*','*',' ',' ',' ',' '},
        { '*','*','*','*','*','*','*'},
        { '*','*','*',' ',' ',' ',' '},
        { '*','*',' ',' ',' ',' ',' '},
        { '*',' ',' ',' ',' ',' ',' '},
};
char arr6[7][7];
char arr9[7][7];

DisplayArray2D(arr);
RotateArray2D(arr6,arr);
DisplayArray2D(arr6);
RotateArray2D(arr9,arr6);
DisplayArray2D(arr9);

}

void DisplayArray2D(char arr[][7]){
    for (int i = 0; i < 7; i++)
    {
        for (int j = 0; j < 7; j++)
        {
        printf("%c",arr[i][j]);
        }
    printf("\n");
    }
}

void RotateArray2D(char arrRotated[][7], char arrOriginal[][7]){
    for (int i = 0; i < 7; i++)
    {
        for (int j = 0; j < 7; j++)
        {
            arrRotated[j][i] = arrOriginal[i][j];
        }
    }
    // DisplayArray2D(arrRotated);
}

Thanks guys, your comments really helped. indeed I was missing the [6-i] in the function in order to rotate the right way.
