It has the following signature: void SortByPrice(std::vector<Snack>& list_ref, bool asc). This function should sort the vector list_ref based on the price_ of the Snacks. The sorting should be done in the following order: Ascending if asc is true Descending if asc is false. In both cases if variables have the same value for price_, the sorting should be done based on the name_ in ascending order.

If the value of price is greater or equal to 0, proceed as follows: If the value passed by price is smaller than the current value of price_, the function should assign price to price_ and return -1. If the value passed by price is larger than the current value of price_, the function should assign price to price_ and return 1. If price is equal to price_, the function should assign price to price_ and return…
