I hope you are doing well. I have got a lot of WhatsApp group links, more than 2000. I need to join all these links at once. I checked about Google Chrome extension that can open multiple links at once, but WhatsApp got a pop-up that asks to join the group or cancel. Is there ..

For the two for loop below, are they equivalent? Basically does the auto look over "=0" assignment and see iter is compared with s.size() and so decides iter is of type decltype(s.size())? string s; for(auto iter=0; iter<s.size();iter++) string s; for(decltype(s.size()) iter=0; iter<s.size();iter++) Source: Windows Que..

Hi i am working with 2D and 1D arrays in C++ and using range for to access elements.The code that i am using is as follows: For 2D Arrays int ia[3][4] = { { 1, 2, 3 }, { 4, 5, 6 }, { 7, 8, 9 } }; for (auto& row : ia) { ..
ssc_event_cb_ts get_ssc_event_cb() { return [this](const uint8_t *data, size_t size, uint64_t ts) { UNUSED_VAR(ts); handle_ssc_event(data, size); }; } I can guess that the function get_ccs_event_cb is to return one anonymous function . If I want to learn more about this kind of declaration, what topic should I learn? Source: Windows Que..
I am reading about pointers and got confused in one part. The code given is as follows: int i=0; const int ci = i; auto *p = &ci;` Now the question is what will be the type of p? I am thinking that p will be a pointer to const int. Is this correct? And ..
Hi i am reading about auto and const in C++ and came to know about 2 examples. The 2 examples are as follows: auto &h = 42; const auto &j = 42; Now my questions are as follows: Why in the 1st example a plain reference cannot be bind to a literal and this example ..
(This question has been broken out from the discussion to this answer, which highlights CWG 1892) Some paragraphs of the standard applies specific rules to function declarators; e.g. [dcl.spec.auto]/3 regarding placeholder types [emphasis mine]: The placeholder type can appear with a function declarator in the decl-specifier-seq, type-specifier-seq, conversion-function-id, or trailing-return-type, in any context where such ..
I was trying to test auto type deduction. Both Scott Meyers (Effective modern C++) and Bjarne Stroustrup’s C++ Programming Language mention that doing auto val {10}; will deduce val to be of type "initialisation list". I read that this was changed in C++17 so that if there is only one element in the list, then ..
I am currently translating an C++ application into Java code, but i got stuck with this method (shortened): int Triangle_ClipAgainstPlane(vec3d plane_p, vec3d plane_n, triangle &in_tri, triangle &out_tri1, triangle &out_tri2) { // Make sure plane normal is indeed normal plane_n = Vector_Normalise(plane_n); // Return signed shortest distance from point to plane, plane normal must be normalised ..
