};
void Location::init(int initx, int inity)
{

}
int Location::Getx()
{
return x;
}
int Location::Gety()
{
return y;
}
void display(Location &rL)
{
cout << rL.Getx() << " " << rL.Gety() << endl;
}
int main()
{
Location A[5] = { {5,5},{3,3},{1,1},{2,2},{4,4} };
Location *rA = A;
A[3].init(7,3);
rA->init(7,8);
for (int k = 0; k < 5; k++)
