## +23 ## Optimizing Away Virtual Functions May Be Pointless ## SHACHAR SHEMESH Slide #2 - who am I?  ## DO NOT ENTER reviewer's notes: There are interesting technical details and surprising conclusions that virtual functions can be actually faster. Since CPU architectures are mentioned, I'd expect to see deep assembly vtable lookup. Does it even matter? ### WEKA DriveU.auto ## Conclusions - The notion that “virtual functions are slower” is flat out wrong. ○ Which is not to say they are faster o Some of the suggested alternatives

Static (the name stands for standard input-output library). This library gives us access to input/output functions. C is a very small language at its core, and anything that's not part of the core is provided abstracts many of the low level details of working with strings, and provides us a set of useful functions. You can load the library in your program by adding on top: #include And

Idris Tutorial Version 1.3.3 ## Contents 1 Introduction 2 2 Getting Started 3 3 Types and Functions 5 4 Interfaces 22 5 Modules and Namespaces 31 6 Packages 35 7 Example: The Well-Typed Interpreter Main.main : IO () *hello> :c hello *hello> :q Bye bye $ ./hello Hello world ## 3 Types and Functions ### 3.1 Primitive Types Idris defines several primitive types: Int, Integer and Double for numeric writing Idris programs both the order in which definitions are given and indentation are significant. Functions and data types must be defined before use, incidentally each definition must have a type declaration

## PyWebIO PyWebIO provides a diverse set of imperative functions to obtain user input and output content on the browser, turning the browser into a “rich text terminal”, and can be used to build simple This is just a very simple script if you ignore PyWebIO, but after using the input and output functions provided by PyWebIO, you can interact with the code in the browser: Your Height(cm): Submit | Reset - pywebio.input — Get input from web browser - Functions list - Functions doc - pywebio.output — Make output to web browser - Functions list - Output Scope - Content Outputting
