因为mapped_type、key_type和const_iterator是依赖于类型模板参数C的名称,所以需要告诉编译器它们标识类型。我们使用typename关键字来做到这一点。 访问存储在 boost::optional 中的值 您可以检查optional对象是否包含值或为空,并提取非空optional对象中存储的值: 1 std::string artiste("Korn"); 2 boost::optional<...
MSC37-C Ensure that control never reaches the end of a non-void function. MSC38-C Do not treat a predefined identifier as an object if it might only be implemented as a macro. MSC39-C Do not call va_arg() on a va_list that has an indeterminate value. MSC40-C Do not viol...
coarray< coarray<int[20]>[10] > weird; In a dynamically-sized coarray declaration, the extent of the leading dimension is left unbounded. The size of this extent cannot be part of the template type because it is not known at compile time. Instead, the size is passed as a constru...

Subscript strength reduction (option −Os/−OS) An array of pointer subscripted with a loop iterator variable (or a simple linear function of the iterator variable), is replaced by the dereference of a pointer that is updated whenever the iterator is updated. ••••••••...

Try putting your division into a function(x,y) in a different file (so the optimizer cannot look at the arguments actually passed) and then calling the function from the original file with (100,0). If you can rebuild the dll, generate a link map (link /MAP); this will help you ...
