Why is this code not working?Help me solve Errors

int bounds(int x,int y,int n)
{
    if((x>=1 && x<=n)&&(y>=1 && y<=n)) return 1;
    else return 0;
}
// Complete the queensAttack function below.

    int _x=r_q,_y=c_q,count=0,f=1;
    for (int i=0;i<8;i++)
    {
        while(f)
        {
            _x=r_q+dx[i];
