I’m starting now with c#, and trying to understand some basics to get going, so i’ve made a simple contact list prototype (i am using Windows Forms): The problem: I ..
I am trying to store a vector of objects and sort them by a string member possessed by each object. It doesn’t need to be sorted alphabetically, it only needs to group every object with an identical string together in the vector. IE reading through the vector and outputting the strings from beginning to end ..

I have many function definitions which I have placed in different cpp files with function declarations in their respective .h files. I have a set of a variables which I have placed in a .h file.

I am writing an implementation of binary tree in C++. I have written the implementation in Python but I am not able to understand how to refer to an object inside the class in C++. for example, in Python the code to insert a node would be: def insert( self, val): if self.data == val: ..
I was trying to understand how objects create and initialize constructors.

Im writing a cube voxel like game and wanting to get more performance. Currently I create the cubes like this for (size_t i = 0; i < 20000; i++) { objects* cube = new objects; cube->position.x = ———- cubes.push_back(cube); } and then I loop through all the objects to change their positions and stuff and ..
My first question is that the object A(v) that added the the map, it should be deleted automatically when exit the scope? My second question is what would happen to the object added into the map, when program exits? I believe when I do a_[name] = A(v);, a copy is stored to the map. Also, ..
