I know this is quite easy trigonomety, however I was never introducted to vectors etc, and I\'m at a loss understanding how this works.
I need to wrap a dynamically allocated array(from a = new double[100] for example) into std::vector(preferably) without copying t开发者_如何学Pythonhe array.
Is there any equivalent f开发者_C百科unction of memset for vectors in C++ ? (Not clear() or erase() method, I want to retain the size of vector, I just want to initialize all the values.)Use std::fil
I have the following vector: tmp3 <- c(\"1500 2\", \"1500 1\", \"1510 2\", \"1510 1\", \"1520 2\", \"1520 1\", \"1530 2\",
This is a piece of my code, I have more class like MathStudent, ArtStudent, etc. which inherits Student class. When I tried to compile, it says \"forbids declaration of `vector\' with no type,\" what
Consider this simple code: class A { }; class V1: vector&开发者_如何学Pythonlt;A *>{ // my nice functions
ive defined the following and filled it with elements: vector <vector<double> > my_vector;
I\'m wondering if this code will do any trouble: I have a vector that is shared among many threads. Every time a thread has to add/remove stuff from the vector I do it under a synchronized block. H开
