Note 2 to [expr.const]/2 implies that if we have a variable o such that: the full-expression of its initialization is a constant expression when interpreted as a constant-expression, except that if o is an object, that full-expression may also invoke constexpr constructors for o and its subobjects even if those objects are of non-literal class ..
I found a solution on Understanding how the function traits template works. In particular, what is the deal with the pointer to member function to get type of function parameters types by using templates. But following code gets "error C2760: syntax error: unexpected token ‘<‘, expected ‘declaration’" on VS2019. It works on GCC ? When ..
I am trying to code task manager and i stuck with %CPU for each process dy PID. I wrote something like, that: static float CalculateCPULoad(unsigned long long idleTicks, unsigned long long totalTicks) { static unsigned long long _previousTotalTicks = 0; static unsigned long long _previousIdleTicks = 0; unsigned long long totalTicksSinceLastTime = totalTicks – _previousTotalTicks; ..
I am looking for the functionality of the following conversion in python between Euler angles to rotation matrix with Eigen: import numpy as np from scipy.spatial.transform import Rotation as R t = R.from_rotvec(np.array([1, 1, 1])).as_matrix() print(t) which gives array([[ 0.22629564, -0.18300792, 0.95671228], [ 0.95671228, 0.22629564, -0.18300792], [-0.18300792, 0.95671228, 0.22629564]]) in c++ my snippet is as ..
Here is my possible implementation of the algorithm std::partition_point is : template <typename In_It, typename FUNC> In_It partitionPoint(In_It b, In_It e, FUNC pred){ int len = e – b; while (len > 0){ int half = len >> 1; In_It middle = b + half; if( pred(*middle) ){ b = middle; ++b; len = len ..
I have problems with codeforces C++ language, it uses Microsoft visual c++ 2017 and usually in other classic C++ compiler programmes like codeblocks and etc. my code works properly but when I submit the code it is error, error occurs when I do problems where I use strings, I can’t use vector strings and strings ..
I am trying to create python bindings for the below struct example { int a = 1; int b = 2; }; This is what I have so far PYBIND11_MODULE(example_python, m) { py::class_<example>(m, "example") .def_readwrite("a", &example::a) .def_readwrite("b", &example::b); } when I checked in python, both a and b are empty, so I tried something like ..

I’ve created a code which demonstrates the First Fit Algorithm using an array of size 256 , the code displays a map showing how the memory is being stored according to the First Fit Algorithm, the code allows the user to delete a memory location too , I would like to create the same concept ..
I recently upgraded Visual Studio 2019 to install the Project Reunion templates so I can run WinUI3 apps. I followed this guide. I believe I installed all the workloads and components from this list but I may have missed something. I installed the templates and they show up when I try to create a new ..
