Convert into c++

[Chad9]

Hello can someone convert this code into c++ code

#include<stdio.h>
#include<malloc.h>

struct Room {
  float length;
  float width;
  float squareFootage;
};

void show(struct Room room) {
  printf("\nsquareFootage : %f", room.squareFootage);
  printf("\nLength : %f", room.length);
  printf("\nWidth : %f", room.width);
}

float area(float length, float width) {
  return length * width;
}


int main() {

  int SIZE=0;
  static struct Room* rooms;
 
  printf("\nEnter the number of rooms in the apartment :");
 
  scanf("%d", &SIZE);
 
  rooms = (struct Room*) malloc(SIZE * sizeof(struct Room));
  printf("\nEnter the dimensions for each room :\n");

  for (int i = 0; i < SIZE; i++) {
      printf("\n\nRoom %d dimensions", i + 1);
      printf("\nLength :");
      scanf("%f", &rooms[i].length);
      printf("\nWidth :");
      scanf("%f", &rooms[i].width);

      rooms[i].squareFootage = area(rooms[i].length, rooms[i].width);
  }
  float apartmentSquareFootage = 0.0;
  printf("\nDisplaying apartment details :\n");
  for (int i = 0; i < SIZE; i++) {
      printf("\n\nRoom %d dimensions", i + 1);
      show(rooms[i]);
      apartmentSquareFootage += rooms[i].squareFootage;
  }
  printf("\nApartment square footage :%f", apartmentSquareFootage);

  return 0;
}

Fuck you, Chad. Do it yourself for once.

I do what I can by my own.
I don't think you have to be rude, you weren't born a scientist

Maybe you have never programmed with c++ facilities. Here your example coded with some basic c++ techniques. I hope, I made this not for letting you cheating or somewhat manner, but rather giving you a general impression how it could look like. I hope that you are willing and doing some own research if some functions or container classes are unclear to you how to use.

#include <vector>
#include <iostream>

struct Room {
  float length;
  float width;
  float squareFootage() const { return length * width; }
};

// Overloads ostream operator<< for struct Room.
std::ostream & operator<<( std::ostream & os, const  Room & room)
{
    os << "\nsquareFootage : " << room.squareFootage()
       << "\nLength : " << room.length
       << "\nWidth : " << room.width;
       
    return os;
};


int main() {

  int SIZE=0;
 
  std::cout << "\nEnter the number of rooms in the apartment :";
  std::cin >> SIZE;
  
  std::vector<Room> rooms( SIZE );
  
  std::cout << "\nEnter the dimensions for each room: \n";

  for ( size_t i = 0; i < rooms.size(); ++i) {
      std::cout << "\n\nRoom " << i + 1 << " dimensions"
                << "\n\nLength :";
      std::cin >> rooms[i].length;
      std::cout << "\nWidth :";
      std::cin >> rooms[i].width;
  }
  
  float apartmentSquareFootage = 0.0;
  std::cout << "\nDisplaying apartment details :\n";
  for (size_t i = 0; i < rooms.size(); i++) {
      std::cout << "\n\nRoom " << i + 1 << " dimensions";
      std::cout << rooms[i];
      apartmentSquareFootage += rooms[i].squareFootage();
  }
  std::cout << "\nApartment square footage :" << apartmentSquareFootage;

  return 0;
}

#include <iostream>

struct Room {
	float length {};
	float width {};
	float squareFootage {};
};

std::ostream& operator<<(std::ostream& os, const Room& room) {
	os << "\nsquareFootage : " << room.squareFootage;
	os << "\nLength : " << room.length;
	os << "\nWidth : " << room.width;

	return os;
}

float area(float length, float width) {
	return length * width;
}

int main()
{
	int SIZE {};

	std::cout << "\nEnter the number of rooms in the apartment :";
	std::cin >> SIZE;

	auto rooms {std::make_unique<Room[]>(SIZE)};

	std::cout << "\nEnter the dimensions for each room :\n";

	for (int i = 0; i < SIZE; ++i) {
		std::cout << "\n\nRoom " << i + 1 << " dimensions";
		std::cout << "\nLength :";
		std::cin >> rooms[i].length;

		std::cout << "\nWidth :";
		std::cin >> rooms[i].width;

		rooms[i].squareFootage = area(rooms[i].length, rooms[i].width);
	}

	float apartmentSquareFootage {};

	std::cout << "\nDisplaying apartment details :\n";

	for (int i = 0; i < SIZE; ++i) {
		std::cout << "\n\nRoom " << i + 1 << " dimensions";
		std::cout << rooms[i];
		apartmentSquareFootage += rooms[i].squareFootage;
	}

	std::cout << "\nApartment square footage " << apartmentSquareFootage << '\n';
}

You want to change the output display.

Thank you guys
