Duff's device provides a compact loop unrolling by using the case keyword both inside and outside the loop. This is unusual because the contents of a case statement are traditionally thought of as a block of code nested inside the case statement, and a reader would typically expect it to end before the next case statement.
An indirect branch (also known as a computed jump, indirect jump and register-indirect jump) is a type of program control instruction present in some machine language instruction sets. Rather than specifying the address of the next instruction to execute , as in a direct branch , the argument specifies where the address is located.
In computer programming, a branch table or jump table is a method of transferring program control to another part of a program (or a different program that may have been dynamically loaded) using a table of branch or jump instructions. It is a form of multiway branch.
IF condition THEN goto label. Programming languages impose different restrictions with respect to the destination of a goto statement. For example, the C programming language does not permit a jump to a label contained within another function, [2] however jumps within a single call chain are possible using the setjmp/longjmp functions.
This avoids having to use "fat" function pointers for nested functions which carry both the code address and the static link. [8] [9] [10] This, however, conflicts with the desire to make the stack non-executable for security reasons. In the esoteric programming language Befunge, a trampoline is an instruction to skip the next cell in the ...

A default label consists of the keyword default. Case labels are used to associate an integer value with a statement in the code. When a switch statement is reached, program execution continues with the statement after the case label with value that matches the value in the parentheses of the switch.
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
