Who wrote the answers to this question? They're all wrong.

Here is a perfectly valid struct which has Data, a Function AND a Variables. Compiles and runs under C++ Visual Studio 2013:

struct bin_index
{
long key; // variable
long length; // variable
long offset; // variable
long number = 3; // variable and data

bool operator < (const bin_index & rhs) const // function, used with std::less< bin_index >()
{
return key < rhs.key;
}
};
