The static data members and static member functions aren't quite what I'm going for in this particular instance.

Define assignment operator.

C++ Code Step 1: Preparation For the moment, "comment out" the following under-construction code: In dynamicarray.h: All function prototypes except the constructors and destructor. Keep the member variables (but we will be replacing them shortly). In dynamicarray.cpp: All function implementations except the constructors and destructor. You should also remove (not just comment out) INITIAL_CAP, and replace it with a hard-coded 10 inside the default constructor. This will also eventually go away. In main: Comment out all the code inside the RunPart1Tests function between the linesbool pass = true; and return pass; • Also in main: Comment out all the code in the main function starting with the "Equality comparison" comment and just before the "return 0;" line. Step 2: Replacing member data and the two constructors You're going to replace the current member data (arr, len, and capacity) with a single vector of integers. Remember that vectors keep track of their own size and capacity, so…

C++ Language Create a UML Diagram for the Class Invoice with the provided code. Use <<constructor>> to define constructors, for each function's variable indicate whether it is a string or a integer. include <string> using namespace std; class Invoice{public:Invoice(string, string, int, int); void setPartNumber(string);string getPartNumber();void setPartDescription(string); string getPartDescription();void setQuantity(int); int getQuantity();void setPricePerItem(int); int getPricePerItem(); int getInvoiceAmount();private:string partNumber; string partDescription; int quantity; int pricePerItem; };
