public:
//MyClass{x=0;y=0;}

void set_var(int x,int y);
void Print_m();

};
MyClass::MyClass(int a , int b )
{

}
void MyClass::set_var(int x,int y)
{
this->x = x;
this->y = y;
}
void MyClass::Print_m()
{
cout << "x = " <<this->x << endl;
cout << "y = " <<this->y << endl;
}
int main()
{
MyClass obj1, obj2(5,8);
