No Template Named 'optional' In Namespace 'std'

No template named 'optional' in namespace 'std' - For example, consider the following code example in which the return type of the function template depends on the types of the template. Stream << std::hex << your_int; Experimental work is also under way to implement c++ technical specifications that will help drive the future of the c++ programming language. In many cases, the template is able to infer the type arguments and therefore it isn't necessary to explicitly specify them. Use 's std::hex.if you print, just send it to std::cout, if not, then use std::stringstream. This declaration may appear in block scope, class scope, or namespace scope. A function template is similar to a class template; There is no difference between a type alias declaration and typedef declaration. 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. 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.

Other manips of interest are std::oct (octal) and std::dec (back to decimal). You can prepend the first << with << 0x or whatever you like if you wish. It generates concrete functions based on the template arguments. A slash '/' in a revision mark means that the header was deprecated and/or removed.
