#include <iostream>
#include<iomanip>
using namespace std;

int main()
{
//variable declarations
char milkType;
int numberOfGallons;
double costPerGallon;
  
cout<<"Milk Lovers grocery Store";
cout<<" =========================";
cout<<" Enter the milk type w-Whole t-2percent s-skim";
cin>>milkType;//input milkType

//base on milk type determine its costPerGallon
if(milkType == 'w' || milkType =='W')
costPerGallon = 4;
else if(milkType == 't' || milkType =='T')
costPerGallon = 3.5;
if(milkType == 's' || milkType =='S')
costPerGallon = 3;

cout<<fixed<<setprecision(2);//set decimal precision to 2 decimal placesusing iomanip header file

cout<<" Enter the gallons";
cin>>numberOfGallons;

cout<<left<<" Milk type purchased "<<right<<setw(15)<<milkType;//right manipulator used for justification
cout<<" Gallons purchased "<<right<<setw(15)<<numberOfGallons;
cout<<" Cost per gallon $"<<right<<setw(15)<<costPerGallon;
cout<<" Total $"<<right<<setw(15)<<numberOfGallons*costPerGallon;

cout<<" End of Milk Lovers grocery Store";
