Question

C2143: syntax error : missing ‘;’ before ‘<‘

I might be quite rusty in C++ since I sincerely don’t know the reason of such errors.
The code is actually quite simple. (VS2003)

#include <vector>

class store
{
public:
    vector<int>storage;
};

int _tmain(int argc, _TCHAR* argv[])
{
    return 0;
}

Answer 1

Because you need to add std:: in front of vector:

std::vector<int>storage;

The vector class is inside the std namespace.

Or just add

using namespace std;

which is highly NOT recommended, especially for header files.
