vector in c++ class
#include <iostream> #include <vector> class Object { public: Object() {} ~Object() {} void AddInt(int num) { m_VectorOfInts.push_back(num); } std::vector<int> GetCopyOfVector() { return m_VectorOfInts; } void DisplayVectorContents() { for( unsigned int i = 0; i < m_VectorOfInts.size(); i++ ) { std::cout << "Element[" << i << "] = " << m_VectorOfInts[i] << std::endl; } std::cout << std::endl; } private: std::vector<int> m_VectorOfInts; }; int main() { // Create our class an add a few ints Object obj; obj.AddInt(32); obj.AddInt(56); obj.AddInt(21); // Display the vector contents so far obj.DisplayVectorContents(); // Creates a copy of the classes container you can only really view whats in // the classes vector container. What ever changes you make here wont effect the class. std::vector<int> container1 = obj.GetCopyOfVector(); // These elements wont be added as it's a copy of the container container1.push_back(342); container1.push_back(64); container1.push_back(123); // Display the classes container to see show nothing was added. obj.DisplayVectorContents(); return 0; }
