 A narrowing conversion can be okay when you know the possible range of converted values can fit in the target. In this case, you know more than the compiler does. If you make a narrowing conversion intentionally, make your intentions explicit by using a static cast. Otherwise, this error message almost always indicates you have a bug in your code. You can fix it by making sure the objects you initialize have types that are large enough to handle the inputs.
 
-The following sample generates C2397 and shows one way to fix it:

-// Compile by using: cl /EHsc C2397.cpp
-#include <vector>
