  • Default value for bool in c++

    - by greenguy1090
    I'm redesigning a class constructor in C++ and need it to catch an unspecified bool. I have used default values for all of the other parameters, but from my understanding bool can only be initialized to true or false. Since both of those cases have meaning in the class, how should I handle checking for change from a default value?

  • Perl check for the existence of a value in a regular array

    - by Mel
    I am trying to figure out a way of checking for the existence of a value in an array without iterating through the array. I am reading a file for a parameter. I have a long list of parameters I do not want to deal with. I placed these unwanted parameters in an array @badparams I want to read a new parameter and if it does not exist in @badparams, process it. If it does exist in @badparams, go to the next read.

  • Iterating over key/value pairs in a dict sorted by keys

    - by Helper Method
    I have the following code, which just print the key/value pairs in a dict (the pairs are sorted by keys): for word, count in sorted(count_words(filename).items()): print word, count However, calling iteritems() instead of items() produces the same output for word, count in sorted(count_words(filename).iteritems()): print word, count Now, which one should I choose in this situation? I consulted the Python tutorial but it doesn't really answer my question.

  • Get groups of 4 elements from name value list using LINQ in C#

    I am wanting to loop through this list of name value pairs and grab them in groups of 4. The data would be like: value1 1 value2 1 value3 1 value4 1 value1 2 value2 2 value3 2 value4 2 and it would group it as 1 list that contains value1 1 value2 1 value3 1 value4 1 and another list that contains value1 2 value2 2 value3 2 value4 2 I know this can be done easily with a for loop, but I am wondering if there is a good way to do it with LINQ.

  • how can a __global__ function RETURN a value or BREAK out like C/C++ does

    - by user1684726
    Recently i've been doing string comparing jobs on CUDA, and i wonder how can a global function return a value when it finds the exact string that i'm looking for. I mean, i need the global function which contains a great amout of threads to find a certain string among a big big string-pool simultaneously, and i hope that once the exact string is caught, the global funtion can stop all the threads and return back to the main funtion, and tells me "he did it"! B.T.W., I'm using CUDA C .How could i possibly achieve that, waiting for help.

  • OpenID - How can I use my personal domain as an OpenID provider/forwarder?

    - by John Himmelman
    I read this comment in the OpenID post on the stackoverflow blog. Kibbee says : One nice feature of OpenID that I use is the ability to delegate the openID verification. So I can set up my own domain name, and then put a tiny bit of XML on that page that tells the site (like stackoverflow) to go to some other openid Provider (in my case MyOpenID). The big plus is that I have complete control over my Open ID account. If MyOpenID goes down, I can just switch to another provider. I think anybody who has their own domain name should go for this option. What is this tiny bit of XML that will allow my server to act as an openid provider/forwarder?
