Question

This is definitely really simple. I have been out of C++ for a few years, so I need some help with figuring out why this won’t compile.

I have a class called ‘PointList’. In the header file, I have the following:

public:
    PointList();

private:
    std::vector< Point* > *pl;

In the .cpp file, I have the following:

PointList::PointList()
{
    pl = new vector< Point* >();
}

This does not compile.

Expected type-specifier before ‘vector’
Cannot convert ‘int*’ to ‘std::vector <*’ in assignment
expected ‘;’ before ‘vector’

What gives?

Answer 1

Are you using using declarations. If not you need to prefix vector with namespace std:: in your cpp file
