Given the following code, what will the output be? vector data;int x = 1;for (int i = 0; i < 4; i++){ x *= 2; data.push_back(&x);}for (int i = 0; i < 4; i++) cout

After the following code has executed, which pointers are pointing to data located on the stack? int x = 7;int* y = &x;int* z = &x;y = new int(3);x = 0;int* w = &x;

Which of the following are reasons why we might dynamically allocate data in our program? Mark all that apply.

Given the following: class TestQuestion{ std::string *answers;public: TestQuestion(int count) { answers = new std::string[count]; } ~TestQuestion { // What goes here? }}; How can you properly delete the dynamically allocated memory for an instance of this class?

How do we access the data at the memory address a pointer points to? Or, how do we access the “pointee” of a pointer? 

How many times do you need to deallocate memory (using either delete[] or delete) to prevent this code from leaking? float* myData[3];float* myPtr = nullptr;for (int i = 0; i < 2; i++) myData[i] = new float[10];myData[2] = new float;myPtr = myData[2];
