Answer 1

#include <iostream>
#include <string>


using namespace std;


class Record{


private:
	string manufacture;
	string type;
	float capacity;

		this->manufacture = manufacture;
		this->type = type;
		this->capacity = capacity;
	}


	void add(){
		cout<<"Enter a manufacture: ";
		getline(cin,this->manufacture);
		cout<<"Enter a type: ";
		getline(cin,this->type);
		cout<<"Enter a capacity: ";
