Class: Desk Data members: weight (integer) Write all external function definition required to make the following code compile: Desk d1{30}, d2{}; cin >> d2; if( d1 > d2 )      cout << (++d2) << "\n"; Include a comment for each function indicating if it is a memb

#include <iostream>using namespace std; struct Person{     int weight ;     int height;}; int main(){     Person fred;     Person* ptr = &fred;     fred.weight=190;     fred.height=70;     return 0;} What is a correct way to subtract 5 from fred's weight using the pointer variable 'ptr'?

all operators that can be overloaded can be implemented as either member functions or regular functions. True False

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…

9. Complete the function prototype so that the callback parameter accepts a closure. The closure accepts a String and an Int parameter but does not return anything. func send(to: String, data: String, callback: _____ ) { // function body }
