Hello,
I have a class which contains a vector. This vector is created in a function called "CreateVector". So far, I have created this vector in this function, and returned the vector as a whole. However, because the vector is large, ideally I'd like to be able to return a pointer to the vector. How can I do this? Can you create a pointer to a vector?
Here is what I have so far:
(This is just an example piece of code to demonstrate my problem, the actual CreateVector() function does much more than is shown)Code:#include <vector> using namespace std; class My_Class { private: vector<int*> x; vector<int*> CreateVector() { vector<int*> y(100); for (int i = 0; i < 100; i ++) { y[i] = i * i; } return y; }; public: void SetX() { x = CreateVector(); }; }; in main() { My_Class my_object; my_object.SetX(); return 0; }
What do I need to do so that I can return a pointer to this vector, in order to speed up the program?
Thanks!
