[ad_1] UCHAR stands for unsigned char which is 1 byte in size. PUCHAR stands for unsigned char*. To store a pointer you need 8 bytes (in a 64 bit application). That’s why the size of UCHAR is 1 byte and size of PUCHAR is 8 bytes. Why a pointer is 8 bytes? That’s because in … Read more
[ad_1] There are a couple of reasons why your code can run slower in an MT enviroment: Running code multithreaded adds management overhead compared to running single threaded. Normally you’d hope that the parallelization of the executed code will make up for it in the sense that the overall execution time goes down on a … Read more
[ad_1] Try this : string[] separators = {“<b>”, “</b>”, “\\n”}; string value = “Hi, my name is <b>Dan</b> and i need \\n to separate string”; string[] words = value.Split(separators, StringSplitOptions.RemoveEmptyEntries); [ad_2] solved Function for splitting by substring [closed]
[ad_1] The compare function shall satisfy the principle of weak ordering. Change the function the following way static bool compareStrings( const overview_table &a_timestamp, const overview_table &b_timestamp ) { return a_timestamp.n_timestamp < b_timestamp.n_timestamp; } [ad_2] solved Segmentation Fault while comparing strings
[ad_1] Node* temp = head; while(temp!=NULL){ temp = temp->next; } This will guarantee that the only way you get out of this loop is if temp is null. And what do you do on the next line? temp->next = newNode;// I think fault is here. Dereference temp! You probably wanted temp to point to the … Read more
[ad_1] Calculate the direction vectors of both lines and normalize them: d := (x2 – x1, y2 – y2) length = sqrt(d.x^2 + d.y^2) d := (d.x / length, d.y / length) Then, you have multiple options to calculate the angle. One simple way is to use the dot product: dot = dRed.x * dGreen.x … Read more
[ad_1] Here’s a possible solution: Use the same name, just at different scopes. #include <iostream> #define LOG(x) do { log() << (x) << ‘\n’; } while(false) std::ostream & log() { return std::clog; } struct Identifier { std::ostream & log() { return ::log() << id << “: “; } int id; explicit Identifier(int n) : id(n) … Read more
[ad_1] You need an array, you can’t do it like that: int i = 2; // get the input from somewhere var values = new string[i]; But that doesn’t mean it’s not possible.You can even create dynamic assemblies,classes,properties,if you really want to.See this documentation for more details: Emitting Dynamic Methods and Assemblies [ad_2] solved Dynamically … Read more
[ad_1] You use of strtok() is wrong: line = strtok(buffer, NULL); should be line = strtok(NULL, delim); Another mistakes should be fixed similarly. The elements of text_lines are uninitialized: text_lines = malloc(6000 * sizeof(char*)); this allocated 6000 pointers to char, but none of these pointers are initialized. 0 [ad_2] solved where is the pthread segfault … Read more
[ad_1] You can use HttpServerUtility.UrlDecode() Server.UrlDecode(Request.QueryString[“title”]).Replace(“_”, ” “); 3 [ad_2] solved Display query string asp.net
[ad_1] The line vector<int> list3(list1.size()+list2.size()); creates a vector of type int and inserts list1.size()+list2.size() default contructed elements. You want to create an empty vector of type int and reserve memory for list1.size()+list2.size() elements. Use vector<int> list3; list3.reserve(list1.size()+list2.size()); [ad_2] solved Some problem about the algorithm of merging two lists
[ad_1] Why is sizeof array(type string) 24 bytes with a single space element? Because the size of a std::string object is 24 bytes (on your system). My understanding is that a char is 1 byte Correct. a string is 2 bytes (an extra byte for the \0 character). An array of 2 char objects is … Read more
[ad_1] You can end a sleep early by waiting on a condition variable and then signalling that condition variable when the mouse button is clicked. Here is some proof-of-concept code which should show you how to do it: #include <chrono> #include <thread> #include <condition_variable> #include <mutex> #include <iostream> using namespace std::chrono_literals; std::chrono::time_point <std::chrono::steady_clock> start_time; std::condition_variable … Read more
[ad_1] No need to create a new array, just Concat the two arrays and then use Write instead of WriteLine: foreach(var res in arr1.Concat(arr2) { Console.Write($”{res} “); } 1 [ad_2] solved console.writeline values of array on one line [closed]
[ad_1] private members, pointers or otherwise, are data that the object either does not want messed by anyone else with or wants to know if someone messed with them. Setter and getter methods allow access to the private member, but in a controlled manner. For example if you have a private integer that under no … Read more
