Please ensure your pull request adheres to the following guidelines:

1. No tabs, Use only spaces, and indent 4 space at a time.
2. No using namespace std;
3. Put spaces after each semicolon, around operators.

for(auto i=0;i!=size;++i) 		     // Bad
for (auto i = 0; i != size; ++i) 	  // Good
auto epsilon=2*gamma-delta*pi;	     // Bad
auto epsilon = 2 * gamma - delta * pi; // Good

4. Put braces to next line in function(such as main()), otherwise, End of line.

int main()
{
    Sales_item total;
    if (std::cin >> total) {
        Sales_item trans;
        while (std::cin >> trans) {
            //...
        }
    }
}
