C++

Define the following operator overloads in ShoppingCart.hpp and implement them accordingly in ShoppingCart.cpp.

/**
   Implements Greater Than Comparison
   A ShoppingCart is greater than another ShoppingCart if the total cost of its items is greater.
   @param a_cart to be compared with this (the calling) cart
   @return true if the total cost of this (the calling) cart is greater than the total cost of items in a_cart.
**/
bool operator>(ShoppingCart a_cart);

/**
   Implements Less Than Comparison
   A ShoppingCart is less than another ShoppingCart if the total cost of its items is less.
   @param a_cart to be compared with this (the calling) cart
   @return true if the total cost of this (the calling) cart is less than the total cost of items in a_cart.
**/
bool operator<(ShoppingCart a_cart);

Answer #1

Below are the simple implementation of the two operator overloaded functions. I am assuming there is a member variable by the name total_cost that store the total cost of the shopping cart object.

Let me know for any changes or query.

==================================================================

bool ShoppingCart::operator>(ShoppingCart a_cart){

   return this->total_cost>a_cart.total_cost;

}

==================================================================

bool ShoppingCart::operator<(ShoppingCart a_cart){

   return this->total_cost<a_cart.total_cost;
}

==================================================================

Indicate whether each of the following statements is true or false and explain why. A competitive firm that is incurring a loss should immediately cease operations. A pure monopoly does not have to worry about suffering losses because it has the power to set its prices at any level it desires. In the long run, firms operating in perfect competition and monopolistic competition will tend to earn normal profits. Assuming a linear demand curve, a firm that wants to maximize...
