Write code that uses a std::map to create a food inventory. We will use a food's name as the key to store the corresponding quantity. Add the following information to the map: 1 Apple, 5 bananas, and 3 milk. Ask the user for the updated number of bananas in the inventory and update the map accordingly. Use the map to display the quantities of each item. #include #include int main() { int new_banana_count = 0; // TODO: Instantiate a std::map using its default constructor to represent a food inventory. // TODO: Add 1 Apple, 5 Bananas, and 3 Milk to the food inventory. std::cout << "Updated amount of bananas: "; std::cin >> new_banana_count; // TODO: Update banana count std::cout << "Number of apples: "; // TODO: Display number of apples std::cout << "\nNumber of bananas: "; // TODO: Display number of bananas std::cout << "\nNumber of milk: "; // TODO: Display number of milk return 0; }

int main() {
int new_banana_count = 0;
// TODO: Instantiate a std::map using its default constructor to represent a food inventory.
// TODO: Add 1 Apple, 5 Bananas, and 3 Milk to the food inventory.
std::cout << "Updated amount of bananas: ";
std::cin >> new_banana_count;
// TODO: Update banana count
std::cout << "Number of apples: ";
// TODO: Display number of apples
std::cout << "\nNumber of bananas: ";
// TODO: Display number of bananas
std::cout << "\nNumber of milk: ";
// TODO: Display number of milk
return 0;
}
In this code, we first instantiate a `std::map` using its default constructor to represent a food inventory. We then add 1 Apple, 5 Bananas, and 3 Milk to the inventory by assigning them to their corresponding keys in the map.
Next, we ask the user for the updated number of bananas and store it in the `new_banana_count` variable. We then update the number of bananas in the map by assigning the `new_banana_count` value to the "Banana" key.
Finally, we use the map to display the quantities of each item by accessing the values of their corresponding keys and printing them to the console.
