Question

#include <string>
#include <iostream>
#include <vector>
class Snack{
public:
Snack(std::string, float, bool);
int set_price(float);
void set_expired(bool);
void set_name(std::string);
std::string name() const{return name_;}
float price() const{return price_;}
bool expired() const{return expr_;}
int how_many_for_ten();
private:
std::string name_;
float price_;
bool expr_;
};
void SortByPrice(std::vector<Snack>&,bool);

Task:

Implement a function working with Snack objects that are stored using a vector. 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.
