Examples of, and arguments for, Jump Tables via Function Pointer Arrays in C/C++; Example code generated by 'Switch/Case' branch table in C, versus IF/ELSE. Example code generated for array indexing if structure size is divisible by powers of 2 or otherwise. "Arrays of Pointers to Functions" by Nigel Jones
HipHop for PHP (HPHPc) is a discontinued PHP transpiler created by Facebook.By using HPHPc as a source-to-source compiler, PHP code is translated into C++, compiled into a binary and run as an executable, as opposed to the PHP's usual execution path of PHP code being transformed into opcodes and interpreted.
One thing the most visited websites have in common is that they are dynamic websites.Their development typically involves server-side coding, client-side coding and database technology.
In Fortran, a computed GOTO jumps to one of several labels in a list, based on the value of an expression. An example is goto (20,30,40) i . [ 44 ] The equivalent construct in C is the switch statement , and in newer Fortran a SELECT CASE construct is the recommended syntactical alternative. [ 45 ]
A label is an explicit name or number assigned to a fixed position within the source code, and which may be referenced by control flow statements appearing elsewhere in the source code. A label marks a position within source code and has no other effect. Line numbers are an alternative to a named label used in some languages (such as BASIC).
Client- and server-side validation; Contains various security features to avoid Cross-site scripting and Cross-site request forgery (CSRF) vulnerabilities; Includes a compact C++ ORM-layer ("Wt::Dbo") Uses the WebSocket networking protocol, if available, for Client–server model of communication, with fallbacks to Ajax or plain web page rendering
Ctags is a programming tool that generates an index file (or tag file) of names found in source and header files of various programming languages to aid code comprehension. Depending on the language, functions , variables , class members, macros and so on may be indexed.
For instance, based on program input, a value could be looked up in a jump table of pointers to code for handling the various cases implied by the data value. The data value could be added to the address of the table, with the result stored in a register. An indirect jump could then be made based on the value of that register, efficiently ...
