Vector Help

Say i have code like below:

Code:

---

        vector<int> test;
        test.push_back(1);
        test.push_back(2);

        for(size_t i = 0; i < test.size(); ++i)
                cout << test[i] << endl;

---

Which prints out:
1
2

Ok no problem. But if i change it so i have a pointer to a vector of int's like this:

Code:

---

        vector<int> *test;
        test->push_back(1);
        test->push_back(2);

        for(size_t i = 0; i < test->size(); ++i)
                cout << test[i] << endl;

---

I get this error:

Code:

---

Error        1        error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::vector<_Ty>' (or there is no acceptable conversion)        d:\school\comp446\project\genalib\genalib.cpp        18

---

So how would i use the [] operator of the vector stl templates when i use a pointer to a vector or int's? Would i have to use test->at(i)? It works if i do that but im just wondering if i can use the [] operator or not.

Blind guess, dereference the pointer:

Code:

---

    cout << (*test)[i] << endl;

---

thanks, it tried to do that like this:

Code:

---

cout << *test[i] << endl;

---

But yeah, i understand now :)
