A type, introduced in PEP 593 (Flexible function and variable annotations), to decorate existing types with context-specific metadata (possibly multiple pieces of it, as Annotated is variadic).

This can usually be done without compromising run-time and space efficiency compared to lower-level techniques. To gain the benefits of C++, programmers …
WebC++ Metaprogramming library If T and U name the same type (taking into account const/volatile qualifications), provides the member constant value equal to true. Otherwise value is false . Commutativity is satisfied, i.e. for any two types T and U, is_same::value == true if and only if is_same::value == true . WebJun 1, 2015 · 3 Answers Sorted by: 2 First of all, the std::isdigit function checks if a character is a digit. Secondly, by using the input operator >> you will make sure that the input is a number, or a state flag will be set in the std::cin object. Therefore do e.g. while (std::cin >> num) numberStack.push (num);
WebIs there any way that I can discover the type of a variable automatically in C, either through some mechanism within the program itself, or--more likely--through a pre-compilation script that uses the compiler's passes up to the point where it has parsed the variables and assigned them their types? I'm looking for general suggestions about this.
