   • definition of static class function outside of class definition

     Answered Feb 28, 2012 · 6 votes

     C++11 standard §9.3 [class.mftc] p3:

     [...] Except for member function definitions that appear outside of a class definition, and except for explicit specializations of member functions of class templates and member function templates (14.7) appearing outside of the class definition, a member function shall not be redeclared.

     Aside from that, you'll get a linker error due to multiple definitions of A::aa, but it seems that you expected that, judging from your last sentence.

   • Definition of Done(DoD) vs Definition of Ready(DoR)

     In Agile Scrum project development practice the terms Definition of Done (DoD) and Definition of Ready (DoR) are both crucial in managing product workflow and execution. These methodologies help to ensure the work is well planned, executed, and completed by the Scrum Team. The Definition of Done and Definition of Ready have their purpose and criteria set by the Scrum team.

     Introduction to Definition of Done

     The definition of done in Agile scrum defines the criteria to be met for a product increment or a sprint to be considered as ‘Done’. The definition of done is part of the sprint review process and sets the criteria for a completed backlog item in a sprint to be considered releasable. It helps to deliver the best quality and avoid any re-work and bugs after delivery. This applies to the end of the sprint for passing all quality standards and delivery guidelines.

     Components of Definition of Done

     Below is the list of key components in the definition of done:

     Code Completion:...

     • Code Completion: Front-end and Back-end codes for all User Stories are fully completed and all coding standards are followed.

   • definition of base has to precede definition of derived contract

     Top Answer

     Answered May 07, 2021 · 4 votes

     You are instantiating a contract inside another contract which is inhering the callee. Kinda circular reference.

     When you inherit a contract(Project1) from a base contract (Project 2), the inheriting (Project1) should be the one that makes the calls. Your (Project2) contract acts like a base contract. The inheriting contract (Project1) can call or override all the functions in the base contract if needed. So here my suggestions (it's one way among many to solve your problem). See below. I compiled it and deployed and it works. Don't forget to provide an address when deploying. I hope this would help. If you have other questions you reach to me.

     // SPDX-License-Identifier: GPL-3.0pragma solidity >=0.7.0 <0.9.0;pragma experimental ABIEncoderV2;-contract Project2{- struct Apple{ string name; bool applepie; //mapping (address => bool) applepie; } Apple[] public applepies; Apple public newProject; constructor() { //address newProject1Address = address(new Project1(msg.sender));- //uint idx = applepies.length; newProject = Apple("superApple", true); applepies.push(newProject); }- function getNewProject() public view returns(string memory){ return newProject.name; }- }--contract Project1 is Project2{ address public creator;- constructor (address creator1){ creator= creator1; }- function getDetails(uint index) public view returns (string memory){ Apple storage newv= applepies[index]; //require(newv.applepie = msg.sender); return newv.name; }}-

   • Definition of variable inside loop

     Top Answer

     Answered Nov 19, 2015 · 3 votes

     The difference is in terms of scope of the variable.

     In the first case, once the while loop ends, the variable k cannot be accessed.

     In the second case, the variable k can be accessed out of the while loop.

     In both cases, the variable is defined on the stack (or as TartanLlama points out, they could be allocated in registers) and so there is no difference in terms of performance.

     However, the example you've used is wrong in the case that the while loop will never end. I'm guessing this is just a piece of dummy code to explain the situation.

   • Definition of "lisp form"?

     Top Answer

     Answered May 20, 2010 · 54 votes

     A lisp form is a lisp datum that is also a program, that is, it can be evaluated without an error.

     (3 4 1)-

     Is a lisp datum, it's a list of 3, 4 and 1. This is not a form however as trying to evaluate it does not result into another datum. But rather an error.

     3-

     Is a datum, and a form, also called a 'normal form' or a 'self-evaluating datum', it evaluates to itself.

     (+ 3 4 1)-

     Is a compound form, evaluating it results into the normal form 8.

     Apart from normal forms and compound forms, compound forms can be subdivided into procedure calls and special forms (also called syntax) but more properly, the head of a special form is the syntax, as in:

     (if (oddp 2) (print "me") (print "or me"))-

     This is a special form because it's head is syntax, and not a procedure, the only difference between procedure calls and special forms is that procedure calls see all of the arguments of the form as forms in itself and try to evaluate it first and special forms not necessarily do that. As we understand, only the second and fourth member of this compound form get evaluated, the first member is syntax, and the third is discarded in this case. As we know for instance:

     ((a 1) (b 2))-

     Is not a form in Common Lisp, it could be a valid form in Scheme, but only if the form (a 1) evaluates to a procedure datum. So:

     (let ((a 1) (b 2)) (+ a b))-

     Is a special form, it does not evaluate its second member, and evaluates its third member in a different fashion than what would be expected if it was not a special form. That is, a and b as subforms of its third form have a different binding. let in this case is a syntactic keyword that signals the special form.

     Note that it's quite possible that special forms still evaluate all of their arguments, they are still not procedure calls then, because their head is syntax, and procedures can be passed to other functions as arguments, syntax cannot, thus:

     (func arg1 #'let)-

     Is an error, likewise:

     (funcall let ((a 1) (b 2)) (+ a b))-

     Is an error, showing that it's different to a procedure call.

   What is a computer instance?

   • A computer instance is an occurrence of a virtual machine which typically includes storage, a virtual CPU . A computer graphics polygonal model can be instantiated in order to be drawn several times in different locations in a scene which can improve the performance of rendering since a portion of the work needed to display each instance is reused.
