How do I fix the last If statement

I'm trying to do tic-tac-toe game using matrix, but the conditions for winning don't work. How do I fix it?

I have already tried If(){}else{}.

void win(int a[SIZE][SIZE], int* win){
        if(a[0][0]==1 && a[0][1]==1 && a[0][2]==1){
            *win=3;
        }
        if(a[0][0]==1 && a[1][0]==1 && a[2][0]==1){
            *win=3;
        }
        if(a[0][1]==1 && a[1][1]==1 && a[2][1]==1){
            *win=3;
        }
        if(a[0][2]==1 && a[1][2]==1 && a[2][2]==1){
            *win=3;
        }


}

It should enter the last two if, and put 3 inside of the pointer *win.
