Latihan Pointer

Tentukan hasil program ini dan gambarkan keadaan pointernya, baik untuk pointer p,q dan r;

Beri penjelasan !. Berikan pemisalan sendiri untuk alamat-alamat yang diperlukan.

main(){

            int n = 1;

            int* p = &n;

            int* q;

            int* r;

            int* s;

            cout<<"n = "<<n<<" &n = "<<&n<<endl;

            cout<<"p = "<<p<<" *p = "<<*p<<endl;

            cout<<"&p = "<<&p<<" &(*p) = "<<&(*p)<<endl;

            q = new int;                 //alokasi

            *q = 2;

            cout<<"q = "<<q<<" *q = "<<*q<<endl;

            cout<<"&q = "<<&q<<" &(*q) = "<<&(*q)<<endl;

            cout<<"q = "<<q<<" *q = "<<*q<<endl;

            cout<<"&q = "<<&q<<" &(*q) = "<<&(*q)<<endl;

            delete(q)                      //apa yang terjadi ??

            r = new int;

            *r = 3;

            cout<<"r = "<<r<<" *r = "<<*r<<endl;

            cout<<"&r = "<<&r<<" &(*r) = "<<&(*r)<<endl;

            s=q;

            *s = 4;

            cout<<"q = "<<q<<" *q = "<<*q<<endl;

            cout<<"s = "<<s<<" *s = "<<*s<<endl;

            cout<<"&q = "<<&q<<" &s = "<<&s<<endl;
