I need to iterate through a vector in a const function, and, as my function is called very often, to get more performances I need my iterator to be declared somewhere else than the function, so it doesn't have to get deleted and recreated over and over again. So here is my code: c...
If the vectors are in a 3D plane, use this formulaθ = Cos-1 [(a · b · c) / (|a| |b| |c|)] Apart from the 2D and 3D planes, there is a critical exception you need to know as a programmer. When your vectors are situated within a plane with a known normal vectornrather...
The following is a high-level summary of Canvas and SVG meant to frame a discussion of when to use one particular vector graphic technology over the other.A Comparison of Canvas and SVGCanvasPixel-based (canvas is essentially an image element with a drawing API) Single HTML element similar ...

Tofind common elements between two vectors, we can useset_intersection() function, it accepts the iterators of both vectors pointing to the starting and ending ranges and an iterator of result vector (in which we store the result) pointing to the starting position and returns an iterator pointi...
Actually I am not able to debug the code as it is for the device and running a big code, so i am putting logs and message boxes. In the message box code I have shared the value is coming to be zero. So I am a bit confused...
cartoon a photo. In addition, you won’t need too much time to get used to XnSketch because its software is intuitive and easy to use. Moreover, the software supports a broad range of image files, which enables you to edit your photos regardless of the format in which they are saved....
- On lines 17 and 23, you are trying to access the 2D vector at [0][0], but these elements do not exist. You must solve this first. - In short:You must push_back or resize the outer dimension (outer array) before you push_back or resize the inner array. ...
You could go directly from vector to string 12345678 std::vector<std::vector<char>> char_vector; //Fill with chars std::string result; for(auto& i : char_vector) { for(auto& j : i) { result += j; } } and then if you particularly want a char array, you can use c_str Las...
