Difference between . and :: in C++ for static members?

Possible Duplicate:
When do I use a dot, arrow, or double colon to refer to members of a class in C++?

When I try to access my static variable using Class.Variable I get the error that Error left of 'Variable' must have class/struct/union and when I do Class::Variable I get no error. Although in both cases I get Variable through intellisense. What exactly is the different between . and :: in this case?

Solution

  • Static members of a class can be accessed through two ways

    (a) With instances of class - Use . e.g. obj.variable

    (b) Without instance of class - Use :: e.g. class::variable
