I have the exercise for implement the Softmax function for forward and backward pass but when I run it, it have the bug like this: terminate called after throwing an instance of 'std::invalid_argument' what(): A row can only be accessed on an expression with exact two dimensions Aborted (core dumped) […]
I have a std::variant of possibly repeated types, and I would like to increment the active index of the variant. Here is an example demonstrating what I would like to do: template bool update_variant(std::variant& v, std::tuple& gen) { return visit_with_index([&](auto& e) { if (e.done()) { // we are done with […]

I was developping this function to transform all negative values from a matrix vector to positive values: Version 1: template void abs_matrin(std::vector &x) { typename std::vector::iterator i2; for (typename std::vector::iterator i = x.begin(); i != x.end(); ++i) { for (i2 = i->begin(); i2 != i->end(); ++i2) { #### CODE TO […]
I was trying to make a program to calculate each grade of 5 courses, the total marks of 5 courses, and CGPA and grade. int main(){ int marks; float count = 0; int tot = 0; string grade; float CGPA; for(int i = 1; i
When using the reserve() method with this iterator object, the program produces an unexpected error. When I use the reserve() method without it, it works as expected, but when I use iterator, it doesn’t work at all. the code that works: vector nums{1,2,3,4,5}, numsT{}; numsT.reserve(50); numsT.insert(numsT.begin(), nums.begin(), nums.end() - 1); […]
I'm trying to read two frames (individually stored in binary files frame1.bin and frame2.bin) and create a mp4 video file called "sample.mp4". Problem: The timestamp, instead of starting from 0, is starting from 0.333 (apparently it is the frame duration value). I'm not able to find what is the reason […]
i'am trying to develop addin for word 2024. I have created a dummy dll like this: #include extern "C" int WINAPI wlAutoOpen(void); extern "C" int WINAPI wlAutoClose(void); BOOL APIENTRY DllMain(HMODULE hModule, DWORD ulReason, LPVOID lpReserved) { if(ulReason == DLL_PROCESS_ATTACH) MessageBoxA(0, "from addin", 0, 0); return TRUE; } int WINAPI wlAutoOpen(void) […]
After DLL injection in C++, I get error code 5 when trying to NOP the bytes I want. I think this is an access permission error. What should I do for this? I tried to run the loader as administrator. bool memory::patch_bytes(std::uintptr_t address, std::string_view string_bytes) noexcept { std::vector bytes = […]
I am using Rad Studio 12.2 C++ Builder and am new to FMX TStringGrid and its live bindings and want to know how I can assign a column created at runtime to a specific field in the database binding. I have done this in VCL, but this is much simpler, […]
