Data items are "local".
Consider the following example in C++.
class MyClass
{
public:
void setX(int x)
{
this->x = x;
}
private:
int x;
};
We have an integer variable local to the scope of the class declaration, and we have another integer variable local to our setX() function, though we have no global functions, that's something you want to try to avoid as a general rule of thumb.
