Question

The code should be written in C++.
I included the Class used for this function. Also, please fix the main function if necessary.

Description: This function de-allocates all memory allocated to INV. This will be the last function to be called (automatically by the compiler)
//before the program is exited.

This function also erased all data in the data file. There are other functions that add, process and alter the file; the file printed after those functions will have new data. HOWEVER, this destructor function will delete all those data and the output file will become empty.

class order_record { public:    string cell_number;    string item_number;    double quantity;    double price;    int processing_plant;    double tax_rate;    double order_tax;    double net_cost;    double total_cost; }; class order_class { public:    order_class();    ~order_class();    bool is_Empty();    bool is_full();    int search(const string key);    void add();    void remove(const string key);    void double_size();    void process();    void print();    int count;    int size;    order_record *INV; };

order_class::~order_class() {     // Enter the Code here.    cout << "The destructor has been called\n"; }

int main() { //Test 4:    //destructor will be invoked when object myOrders goes out of scope    cout << "Test 4: Destructor called" << endl;    cout << "End of Test 4" << endl;    cout << "**********************************************************************\n";    cout << "**********************************************************************\n"; }

Answer 1

If you have any doubts, please give me comment...

order_class::~order_class()

{

// Enter the Code here.

for(int i=0; i<count;i++){

remove(INV[i].cell_number);

}

delete(INV);

cout << "The destructor has been called\n";

}
