kandi X-RAY | DiffNum Summary
A light-weight head-only c++ library for differentiable programming. Unlike the popular TensorFlow and Torch, DiffNum is implemented simply with forward inference with chain rule, instead of computation graph, source code transformation or other high level autograd algorithms. Thus it takes few efforts to implement and apply.

Answered 2017-Jul-31 at 06:30They collide because all "tagged types" share one namespace for the tags.
C11 6.2.3 Name spaces of identifiers (N1570 Draft)
If more than one declaration of a particular identifier is visible at any point in a translation unit, the syntactic context disambiguates uses that refer to different entities. Thus, there are separate name spaces for various categories of identifiers, as follows:
- label names (disambiguated by the syntax of the label declaration and use);
- the tags of structures, unions, and enumerations (disambiguated by following any of the keywords struct, union, or enum);
- the members of structures or unions; each structure or union has a separate name space for its members (disambiguated by the type of the expression used to access the member via the . or -> operator);
- all other identifiers, called ordinary identifiers (declared in ordinary declarators or as enumeration constants).
