  • Specializing function template for both std::string and char*

    - by sad_man
    As the title says I want to specialize a function template for both string and char pointer, so far I did this but I can not figure out passing the string parameters by reference. #include <iostream> #include <string> template<typename T> void xxx(T param) { std::cout << "General : "<< sizeof(T) << std::endl; } template<> void xxx<char*>(char* param) { std::cout << "Char ptr: "<< strlen(param) << std::endl; } template<> void xxx<const char* >(const char* param) { std::cout << "Const Char ptr : "<< strlen(param)<< std::endl; } template<> void xxx<const std::string & >(const std::string & param) { std::cout << "Const String : "<< param.size()<< std::endl; } template<> void xxx<std::string >(std::string param) { std::cout << "String : "<< param.size()<< std::endl; } int main() { xxx("word"); std::string aword("word"); xxx(aword); std::string const cword("const word"); xxx(cword); } Also template<> void xxx<const std::string & >(const std::string & param) thing just does not working. If I rearranged the opriginal template to accept parameters as T& then the char * is required to be char * & which is not good for static text in code. Please help !

  • [C++] Is it possible to roll a significantly faster version of sqrt

    - by John
    In an app I'm profiling, I found that in some scenarios this functions are able to take over 10% of total execution time. I've seen discussion over the years of faster sqrt implementations using sneaky floating-point trickery, but I don't know if such things are outdated on modern CPUs. MSVC++ 2008 compiler is being used, for reference... though I'd assume sqrt is not going to add much overhead though.

  • Is there image phase correlation libraries available for Python?

    - by kamasudra
    A project that involves image processing, i.e. to calculate the angular shift of the same image when shifted by a medium of certain Refractive Index. We have to build an app that correlates the 2 images (phase/2D correlation?) and then plot using Chaco and Mayavi (2 libraries in Python). Is there any other existing template software (FOSS) that we can base our app on, or use it as a reference?

  • Overload with different return type in java?

    - by nunos
    So, I am just starting Java and, even though I have looked in some question about it here at stackoverflow.com and elsewhere, haven't been able to find a straightforward answer to why isn't possible to overload a function just by changing the return type. Why is it so? Will that provably change in a future version of Java? By the way, just for reference, is this possible in C++? Thanks.

  • What is the first ORM framework?

    - by user1014315
    I'm doing a presentation about history of software engineering and stuck at this question due to the lack of available information. According to my quick research, TopLink is the first ORM framework ever created (in 1990s, certainly before 1996). If anyone else has a different opinion, please let me know. (Please also provide a link to the reference sources) Ref: http://en.wikipedia.org/wiki/List_of_object-relational_mapping_software http://en.wikipedia.org/wiki/TopLink

  • Ttrigger extra paramter

    - by fire
    According to the jQuery manual you can send extra parameters (as an array) when calling a trigger. I am using this at the moment: $('#page0').trigger('click', [true]); How would I pick up whether the paramter has come through or not when using this? $('ul.pages li a').click(function() { // Do stuff if true has been passed as an extra parameter });

  • Why string.Replace("X","Y") works only when assigned to new string?

    - by Petr
    Hi, I guess it has to do something with string being a reference type but I dont get why simply string.Replace("X","Y") does not work? Why I need to do `string A=stringB.Replace("X","Y") I thought it is just a method to be done on specified instance? Thanks for explanation EDIT: Thank you so far. I extend my question Why "b+="FFF"works but the b.replace is not?

  • Google Drive listing, searching and deleting files

    - by omarshammas
    I'm building a web app that integrates with Google Drive, and am wondering if there was a way to list, search or delete files. I see from https://developers.google.com/drive/v1/reference/files#resource that there are 4 operations. If there are no list and search capabilities then the onus is on the app to handle the management. Is there another API I should be using? Are those features in the works?

    I have few lists like: a = [1, 2, 3, 4, 5] b = [4, 6, 5, 9, 2] c = [4, 7, 9, 1, 2] I want to trim all of them using a loop, instead of doing as below: a[-2:] b[-2:] c[-2:] I tried but got confused with pass by value or pass by reference fundamentals, looked into other questions as well but no help.
