[Solved] expected ‘void (**)(void *, const char *)’ but argument is of type ‘void (*)(void *, const char *)

[ad_1] It is pretty wonky, it wants to return the default error handler. So you have to pass a pointer to a variable. Like this (untested): xmlGenericErrorFunc handler; initGenericErrorDefaultFunc(&handler); If I understand your intentions properly, this is not the function you actually want to use to suppress errors. Use xmlSetGenericErrorFunc() instead. You can use initGenericErrorDefaultFunc() … Read more

[Solved] Image Shearing C++

[ad_1] I found some time to work on this. Now I understand what you tried to achieve with the offset computation, but I’m not sure whether yours is correct. Just change all the cv::Vec3b to unsigned char or uchar and load as grayscale, if wanted. Please try this code and maybe you’ll find your error: … Read more

[Solved] C program not printing

[ad_1] Your code is buggy! you don’t allocate memory for the bus[] array, and are trying to access values at garbage location as e.g bus[i] = 0; — Undefined Behavior in C standard, Undefined means you can’t predict how your code will behave at runtime. This code compiled because syntax-wise the code is correct but … Read more

[Solved] How to insert a character after every n characters in a huge text file using C#? [closed]

[ad_1] void InsertACharacterNoStringAfterEveryNCharactersInAHugeTextFileUsingCSharp( string inputPath, string outputPath, int blockSize, string separator) { using (var input = File.OpenText(inputPath)) using (var output = File.CreateText(outputPath)) { var buffer = new char[blockSize]; int readCount; while ((readCount = input.ReadBlock(buffer, 0, buffer.Length)) > 0) { output.Write(buffer, 0, readCount); if (readCount == buffer.Length) output.Write(separator); } } } // usage: InsertACharacterNoStringAfterEveryNCharactersInAHugeTextFileUsingCSharp( inputPath, outputPath, … Read more

[Solved] How to check if a IEnumerable is sorted?

[ad_1] One example of such method could be: static bool IsSorted<T>(IEnumerable<T> enumerable) where T : IComparable<T> { T prev = default(T); bool prevSet = false; foreach (var item in enumerable) { if (prevSet && (prev == null || prev.CompareTo(item) > 0)) return false; prev = item; prevSet = true; } return true; } Works with … Read more

[Solved] How to specify type of a constexpr function returning a class (without resorting to auto keyword)

[ad_1] The actual type is hidden as it’s local inside the function, so you can’t explicitly use it. You should however be able to use decltype as in decltype(create<int>()) v = create<int>(); I fail to see a reason to do like this though, when auto works. 1 [ad_2] solved How to specify type of a … Read more

[Solved] How many ways to go up a N-step stairs?

[ad_1] The answer by Code-Apprentice is very good, so I want to contribute a different approach: Writing down the solutions for the first few flight of stairs I quickly noticed a pattern.
