Thread: Linker Error problem

Thanks for the help!
Er...any idea why it won't let me use cout<< on the vector?
I tried:

Code:

cout<<PVec.begin();

and

Code:

cout<<PVec.end()-1;

but I keep getting an error about there not being a match for it. This is in the function PhoneBook::AddPerson(); by the way.

Because you have spots in your vector that contain NULL pointers because no memory has been allocated to your person pointer.

Code:

person *npb;

should be:

Code:

person *npb = new person;

Make sure that when you declare a pointer, that before you use the pointer and store variables in its location that you need to assign the memory using the new operator.

PVec.begin() is an iterator (basically a pointer) to type person. If you had overloaded the stream insertion operator (<<) for type person and you changed the way you were outputting from:

Code:

cout << PVec.begin();

to:

Code:

cout << *PVec.begin();

then it should work.

I already made mention of the fact the OP was not allocating memory to the npb pointer in my first post. I am assuming he corrected that and has now moved on to another seperate issue.
