Thread: Got errors when using iterator. Please help me!

I don't understand why these error occur. Anything wrong with syntax? Please help me! Thank you very much!

btw: I use MS VC++ to compile these code.

Code:

#include <vector>

using std::vector;
using std::iterator;

int main()
{
	vector<int> a(10, -1);
	vector<int>::iterator b = a.begin();
	return 0;
}

a.obj - 4 error(s), 0 warning(s)

it seems to compile fine for me. what compiler are u using

s.s.harish

Microsoft Visual C++ 6

I've found 2 solution. Either to use "using namespace std", or to add "std::" before "vector<int>::iterator b = a.begin();"

Maybe it's because there are some problems with msvc++6
