ArrayList list = new ArrayList(25); What is the type of the ArrayList defined in question number?

This C++ program keeps giving me the wrong median.   #include <iostream> using namespace std; double median_value(int* arrptr, int n); class Median { private: int* array; int n; public: void getSizeArray(); void getNumElements(); void displayMedian(); ~Median() { delete[] array; } }; void Median::getSizeArray() { cout << "How big is array?"; cin >> n; } void Median::getNumElements() { array = new int[20]; for (int i = 0; i < n; i++) { cout << "How much "; cin >> *(array + i); } } void Median::displayMedian() { int m = median_value(array, n); cout << m; } int main() { Median showMedian; showMedian.getSizeArray(); showMedian.getNumElements(); showMedian.displayMedian(); return 0; } double median_value(int* arrptr, int n) { double median; if (n % 2 == 0) { median = (*(arrptr + (n / 2)) + *(arrptr + (n / 2 +1))) / 2; } else { //(arrptr[i]+(n/2)) median = *(arrptr + (n / 2)); } return median; }

int class Inventory { std::vector<Item*> m_Items; static unsigned int m_ItemsMade;   void CreateItem() { std::string name = "Item " + std::to_string(m_ItemsMade); m_Items.push_back(new Item(name.c_str(), 100 * m_ItemsMade)); ++m_ItemsMade; }   public: Inventory() { CreateItem(); CreateItem(); CreateItem(); }   void Print() const { size_t* nSize = new size_t(m_Items.size()); std::cout << "_____INVENTORY_____\n"; for (unsigned int i = 0; i < *nSize; ++i) { m_Items[i]->Print(); } } }; GetValidatedInt(const char* strMessage, int nMinimumRange = 0, int nMaximumRange = 0); This function should first display the provided message to the screen then use cin to get an int from the user. Error check and validate to ensure a legal integer was entered. If not, clear the cin buffer using clear() and ignore() and try again (Note: the buffer still needs to be cleared even if this step was successful). If a legal integer was entered, check its value to see if it is within the…

1. Implement a class IntArr using dynamic memory. a. data members: capacity: maximum number of elements in the array size: current number of elements in the array array: a pointer to a dynamic array of integers b. constructors: default constructor: capacity and size are 0, array pointer is nullptr user constructor: create a dynamic array of the specified size c. overloaded operators: subscript operator: return an element or exits if illegal index d. "the big three": copy constructor: construct an IntArr object using deep copy assignment overload operator: deep copy from one object to another destructor: destroys an object without creating a memory leak e. grow function: "grow" the array to twice its capacity f. push_back function: add a new integer to the end of the array g. pop_back function: remove the last element in the array h. getSize function: return the current size of the array (not capacity) i. Use the provided main function (next page) and output example Notes a. grow…
