values on the output are duplicated CODE: enum class status_t { _success, }; const char* set_status(status_t status) { switch(status) { case status_t::_success: return xorstr_("[SUCCESS]"); } } enum class action_t { _launch, }; const char* set_action(action_t action) { switch (action) { case action_t::_launch: return xorstr_("[LAUNCH]"); } } void record(const char* status, const char* action, char* message) ..

Exist there a function where i can search a file and the program return the path to it in c++ on linux? I tried with dirent.h but i don’t know how to get the path in that recursive search. Thanks! Source: Windows Que..
I wanted to simulate timer which would call a function (callback) periodically for that i wrote following snippet (naive though) wherein, Argument deduction is failing at line Timer/<int, int, float>/.. in main function. I am compiling this code with c++17 std. How I can fix this? or those arguments necessary? Any help in this regard ..
Below is the sample code part. How to mock Registry value for RegOpenKey if (ERROR_SUCCESS == RegOpenKeyEx(HKEY, M_REGISTRY, 0, KEY_READ, &hKey)) { SLI << "ABC if (ERROR_SUCCESS == RegQueryValueEx(hKey, S_TYPE, 0, NULL, (LPBYTE)Value, &dwSize)) { wstrVPN = Value; SLI << "DEF " << wstrVPN.c_str(); } else { SLE << "GHI"; } } Source: Windows Questions ..
Working on a piece of code that assigns points to student based on a condition. the way it works is vector of type Student. Student is struct that contains a double percentage. the vector is sorted based on the highest percentage. I would like to go through the vector and assign 10 points to first ..
I had a class with a std::vector member that had the same name as the class and had no user-defined constructors; later I had a factory method that generated one of these objects: #include <vector> class data { std::vector<int> data; }; data create() { data d{}; // … return d; } When I try to ..
I’m beginner in parallel programming for GPU. I’m trying to implement a convolutional operation between a 512×512 RGB image size and a 9×9 filter. I got an error: illegal memory access was encountered. Here is my kernel function: __global__ void blurImgKernel(uchar3 * inPixels, int width, int height, float * filter, int filterWidth, uchar3 * outPixels) ..
I have a structure that looks like this: class Foo { union { size_t cap; char buff[15]; }; bool isHeap; }; I would like sizeof(Foo) to equal 16, but sizeof(Foo) is 24 on 64 bit computers. I think this is because size_t forces the alignment of the union to be 8, and thus there is ..
I writing a application record voice and I want to put input voice to CMiniportWaveRTStream::WriteBytes in sysvad to the listener can hear instead they hear piippp because in CMiniportWaveRTStream::WriteBytes, function GenerateSine create sin wave: while (ByteDisplacement > 0) { ULONG runWrite = min(ByteDisplacement, m_ulDmaBufferSize – bufferOffset); m_ToneGenerator.GenerateSine(m_pDmaBuffer + bufferOffset, runWrite); bufferOffset = (bufferOffset + runWrite) ..
After a 2 years break, I’ve started using C++ again, and I’m pretty rusty. I’m trying to implement a 5-coloring algorithm for a graph, but I’m having trouble with vectors. I’ve 3 classes (snippets below). The problem is that somewhere in Graph::Graph(), a copy constructor is called on both vectors (While troubleshooting the Graph::solve() function, ..
