setting up a simple template...

[joemoe]

I am stumped on a simple template problem

I copied this code from a book word for word and the code doesn't work. I wonder if there is a typo in the book or maybe I am stupid and missed something but heres the code:
----------------------------------------------------------------------------
#include <set>
#include <iostream>

using namespace std;

template <typename Container>
void displaySet(const Container & input);

int main (int argc, char * const argv[])
{

return 0;
}

template <typename Container>
void displaySet(const Container & input)
{
Container::const_iterator iElement;
//RIGHT HERE I GET (error: expected ";" before 'iElement')
}
------------------------------------------------------------------------------

Ah, the discrepancies between compilers! Microsoft's compiler would happily compile your code but gcc is more conforming to the standard. The Fix:

template <typename Container>
void displaySet(const Container & input)
{
    typename Container::const_iterator iElement;
}

Wow that worked.

Thanks angelorohit.

I use Xcode for compiling is there a site that you might recommend for me to find these differences so that I won't have to bug anyone for small things like this?
