Introductory Audience 3Abstract Pointers are scary. Unfortunately that previous statement is what many beginners take away when first learning about pointers and the C++ language. In this talk, we will discuss )And more.... ● For memory and pointer related best practices on common pitfalls see the ISOCPP guide here: ○ https://isocpp.org/wiki/faq/freestor e-mgmt ● And since we’re on pointers...some tips

micrograd++ retains the educational value of the original micrograd library, making it accessible to both beginners and experienced practitioners in the field of machine learning. The library’s design simplifies

fundamentals of the creational, structural, and behavior design patterns. This talk is aimed at beginners who have some C++ knowledge working on a software project, but are starting to think about larger

libaries! 41Hopefully users of the language don't use reflection much People writing business logic Beginners And hopefully library designers design great APIs that never even let users look at reflection
