No Template Named 'optional' In Namespace 'std'

No template named 'optional' in namespace 'std' - Stream << std::hex << your_int; Use 's std::hex.if you print, just send it to std::cout, if not, then use std::stringstream. Other manips of interest are std::oct (octal) and std::dec (back to decimal). Experimental work is also under way to implement c++ technical specifications that will help drive the future of the c++ programming language. There is no difference between a type alias declaration and typedef declaration. In many cases, the template is able to infer the type arguments and therefore it isn't necessary to explicitly specify them. The clang community is continually striving to improve c++ standards compliance between releases by submitting and tracking c++ defect reports and implementing resolutions as they become available. You can prepend the first << with << 0x or whatever you like if you wish. It generates concrete functions based on the template arguments. For example, consider the following code example in which the return type of the function template depends on the types of the template.

A function template is similar to a class template; A slash '/' in a revision mark means that the header was deprecated and/or removed. In c++11, you can use the decltype type specifier on a trailing return type, together with the auto keyword, to declare a function template whose return type depends on the types of its template arguments. This declaration may appear in block scope, class scope, or namespace scope.
