Given big_num.h and big_num_driver.cpp implement, the big_num class so that the main in big_num_driver.cpp and replace the vector with a dynamic array. You will probably have to add a size variable to the class as well. Also write a copy constructor, operator = and destructor for the big_num class.

USE C++

#include

#include

#include

#include "big_num.h"

int main() {

std::string str;

std::cout

getline(std::cin,str);

big_num x(str);

std::cout

getline(std::cin,str);

big_num y(str);

big_num result = (x+y);

std::cout

std::cout

return 0;

}
