simple... warning in STL!! Why??

Raphael Kindt

Hi all, When I compile this very simple program I get some warnings... but I don't know why? Here is this program:

int i = 0;
std::vector str\_vect1;
std::vector str\_vect2;
std::vector::iterator it1;
std::vector::iterator it2;

// GET str\_vect1
str\_vect1.resize(5);
for(it1 = str\_vect1.begin(), i = 0; it1 != str\_vect1.end(); it1++, i++)
{
	cout << "str\_vect1\[" << i << "\] = ";
	cin >> \*it1;
}

// COPY str\_vect1 into str\_vect2
str\_vect2.resize(str\_vect1.size());
for(it1 = str\_vect1.begin(), it2 = str\_vect2.begin(); it1 != str\_vect1.end(); it1++, it2++)
{
	\*it2 = \*it1;
}

// SHOW str\_vect2
for(it2 = str\_vect2.begin(), i = 0; it2 != str\_vect2.end(); it2++, i++)
{
	cout << "str\_vect2\[" << i << "\] = " << \*it2 << endl;;
}

I don't understand these warnings... Compiling...

Don't worry about it, it's a confirmed (and harmless) bug in MSVC++ 6.0. To get rid of it, insert the following line at the beginning of your .cpp:

#pragma warning(disable:4786)
