structure

问题 I do apologize for the lack of knowledge in this matter but it is very important for me, so at least I'll give it a try. I am using Visual Studio 2012 express on Windows 7 ultimate, I have written some very basic a silly program to practice structures in the C language. Unfortunately, one of the methods that I've written had a wrong condition to stop and it goes to an infinite loop and the worse part it exceeds the given array boundaries. I will add the code below BUT THE CODE IS NOT my main

问题 Following from Way/coding method to do activitylist/log I worked with the accepted answer on above question, by having two tables one for the descriptions of the activities, and other for the activities themselves.. table: activitylist Columns: id, description, date table: activities Column: id, aID, uID, date aID is activity id, uID is user id. activity id is the id in table ´activitylist´ I can now output: person ate another persons apple As this text is non-personal and can be used to all.

问题 I want to call a DLL function that wants a structure, and within that structure is another structure. The Dll should return values to my structures but I get nothing but error codes. One time (some coding back ago) I successfully returned "True" on my function call, but there were no values in my structures. I am not very familiar with marshaling and such, but if someone could please provide me an example on how to do this! The Dll code looks like this:

问题 Let's suppose we have a structure: struct product { char name[30]; float price; }; I want to sort it using qsort first by price, and if the prices are equal, by name. How I thought of writing the compare function: int compare(const void *a, const void *b ) { int comp = a.price - b.price; if (comp < 0 ) return 1 if (comp > 0 ) return 0; comp = strcmp(a.name, b.name); if ( comp < 0 ) return 1; else if ( comp > 0 ) return 0; } Since I have only used the usual compare function for qsort, I don't

问题 This question already has answers here : How do I use a structure? (3 answers) Closed 6 years ago . Ok firstly I'll explain my assignment. For this assignment I have to use dynamic memory allocation which I am having no problems with. What I am having a problem with is figuring out the correct way to work my assignment. For my assignment I need to create a program that prompt the user to enter how many students they have then ask for the following information; Student ID, Birthdate, and Phone

问题 This is a follow-on post to our previous post (Help Structuring VS2010 Solutions/Projects and TFS2010). We have a few questions regarding how to structure our VS2010 solutions and projects for best organization, as well as to save in and use TFS2010. Currently, our code is structured something like: /OverallAppName OverallAppName.sln -/Client - -/WindowsFormsProject1 WindowsFormsProject1.sln - -/WindowsFormsProject2 WindowsFormsProject2.sln -/Components - -/ClassLibrary1 (common library

问题 I'm currently building a CMS system, and I need to have an easy way include or exclude components. My first think was to use asp.net mvc area feature, to identified each component on itself. But from what I see, the area feature has problems, so maybe it not that good idea. 回答1: After a few experience with area feature, I think that areas are best for something entirely different in your site, that not share the same master page with the root area. In my case, that components are an add-ons

问题 I have the following data structure: struct scoreentry_node { struct scoreentry_node *next; int score; char name[1]; }; typedef struct scoreentry_node *score_entry; I am trying to create a function that consumes my structure in order and arranges them in ascending order based on the name. I want to modify the input without allocating any memory or freeing anything: I've tried your suggestions: void selectionsort(score_entry *a) { for (; *a != NULL; *a = (*a)->next) { score_entry *minafteri =

问题 I have a synthetic image. I want to do eigenvalue decomposition of local structure tensor (LST) of it for some edge detection purposes. I used the eigenvalues l1 , l2 and eigenvectors e1 , e2 of LST to generate an adaptive ellipse for each pixel of image. Unfortunately I get unequal eigenvalues l1 , l2 and so unequal semi-axes length of ellipse for homogeneous regions of my figure: However I get good response for a simple test image: I don't know what is wrong in my code: function [H,e1,e2,l1

问题 I've created a structure in Liferay as below <root> <dynamic-element name='header' type='text' index-type='' repeatable='true'> <dynamic-element name='headerlink' type='text' index-type='' repeatable='false'> </dynamic-element> <dynamic-element name='location' type='text' index-type='' repeatable='false'> </dynamic-element> <dynamic-element name='description' type='text_box' index-type='' repeatable='false'> </dynamic-element> <dynamic-element name='date' type='text' index-type='' repeatable=
