The food pantry provides its volunteers with keys to unlock doors and a Food Pantry vest to let customers know they work there. There are a limited amount of keys and vests, so volunteers need to check them out of the office.Complete the program by creating a CheckoutEquipment function that takes in the number of keys and vests currently available at the office. If there are enough keys and vests, the function should reduce the number of keys and vests by 1 and return true. Otherwise, the number of keys and vests will stay the same, and the function will return false. Take note that the number of keys and vests will be defined in the main function and the CheckoutEquipment function should modify the values of those variables declared in main. #include <iostream> int main() {   int keys = 10;   int vests = 10;   bool checked_out = CheckoutEquipment(keys, vests);   if (checked_out) {     std::cout << "Successfully checked out.\n";   } else {     std::cout << "Not…
