• In C and C++, what methods can prevent accidental use of the assignment(=) where equivalence(==) is needed?

  - by DeveloperDon

  In C and C++, it is very easy to write the following code with a serious error. char responseChar = getchar(); int confirmExit = 'y' == tolower(responseChar); if (confirmExit = 1) { exit(0); } The error is that the if statement should have been: if (confirmExit == 1) As coded, it will exit every time, because the assignment of the…

• What's Your Method of not forgetting the end brackets, parentheses

  - by JMC Creative

  disclaimer: for simplicity sake, brackets will refer to brackets, braces, quotes, and parentheses in the couse of this question. Carry on. When writing code, I usually type the beginning and end element first, and then go back and type the inner stuff. This gets to be a lot of backspacing, especially when doing something with many nested…

• Is sending data to a server via a script tag an outdated paradigm?

  - by KingOfHypocrites

  I inherited some old javascript code for a website tracker that submits data to the server using a script url: var src = "http://domain.zzz/log/method?value1=x&value2=x" var e = document.createElement('script'); e.src = src; I guess the idea was that cross domain requests didn't haven't to be enabled perhaps. Also…

• How to choose between Tell don't Ask and Command Query Separation?

  - by Dakotah North

  The principle Tell Don't Ask says: you should endeavor to tell objects what you want them to do; do not ask them questions about their state, make a decision, and then tell them what to do. The problem is that, as the caller, you should not be making decisions based on the state of the called object that result in you then…

• When creating a library for a simple program, what must I do to protect others from its lack of thread safety?

  - by DeveloperDon

  When creating a library for a simple program, is it more cost effective to make it thread safe or is there a way to detect the program's use in a multithreaded program and ASSERT() or otherwise determine (preferably at compile or link time) that it may create problems. Related help for this question would be automated tool support for…

• What is the possible disadvantage of putting declarations in inner blocks, instead of at beginning of function?

  - by shan23

  At the place where I work, there are explicit guidelines for placement of declarations of variables. According to that, it is required to put them at the global level and / or at the beginning of functions, and not in inner blocks (such as a for loop). Since they've been specified by persons more experienced than I am, I'm sure that…

• Bikeshedding: Placeholders in strings

  - by dotancohen

  I find that I sometimes use placeholders in strings, like this: $ cat example-apache <VirtualHost *:80> ServerName ##DOMAIN_NAME## ServerAlias www.##DOMAIN_NAME## DocumentRoot /var/www/##DOMAIN_NAME##/public_html </VirtualHost> Now I am sure that it is a minor issue if the placeholder is ##DOMAIN_NAME##,…

  - by Slomojo

  Possible Duplicate: Make a big deal out of == true? I've been looking at a lot of code samples recently, and I keep noticing the use of... if( expression == true ) // do something... and... x = ( expression == true ) ? x : y; I've tended to always use... x = ( expression ) ? x : y; and... if( expression ) …

• SSD harddisks & programming

  - by Carra

  SSD harddisks have been on the rise lately. And I've been wondering if it's worth buying one as a programmer. Being able to save five minutes when starting my PC is fun but won't convince my boss. How does it impact a typical visual studio project containing hundreds of files? Compile times, accessing files, waiting for visual…

• Checking negative of a condition

  - by oym

  What is the (slightly pejorative) term for checking the negative of a condition (rather than the positive which is often more readable): e.g. if(!someVar) { return null; } else { return doSomethingInteresting(); } instead of doing this (which is arguably more readable) if(someVar) { return doSomethingInteresting(); }…

• Accepting a numerical range in a function call

  - by dekpos

  I have encountered two ways of doing it: void foo(int from, int to); /* 'from' inclusive, 'to' exclusive */ void foo(int startIndex, int rangelength); Has one style historically been preferred over the other? If so, was it just a matter of convention or was it due to some deeper underlying reason? I'm currently programming…

• Should Equality be commutative within a Class Hierachy?

  - by vossad01

  It is easy to define the Equals operation in ways that are not commutative. When providing equality against other types, there are obviously situations (in most languages) were equality not being commutative is unavoidable. However, within one's own inheritance hierarchy where the root base class…

• Naming the implementation version of an interface function

  - by bolov

  When I need to write an implementation version of an interface function, I put the implementation function within a impl namespace, but with the same name as the interface function. Is this a bad practice? (the same name part, the namespace part I am confident it’s more than OK). For me, who I…

  Which is better/more generally accepted? This: if(condition) { statement; } Or: if(condition) statement; I tend to prefer the first one, because I think it makes it easier to tell what actually belongs in the if block, it saves others from adding the braces later (or creating…
