:sad: :sad:

just one extra method will make your code alot better, we will call it FindPrice
so

private double FindPrice(int day, char choice)
{
swich(choice) {
case 's':
case 'S' : //You may want to add output message
if (day >=1 && day <= 10)
return 4.50;
elseif (day >= 11 && day <= 20)
return 4.00;
else // day less than 31
return 3.25


// ... and all the other cases,
//note it would be good if you return -1 with there
//wasn't a match
}

In main call this method like

int price =0;
if (price = FindPrice(day, choice) != -1);
and then ask user for the number of cones and you know the rest
else
wrong choice

this was only a quick answer but i hope this helps

i have read the lil problem and i believe you can improve your code once again by changing FindPrice to FindBasicPrice(char choice), so you just have the switch statements but no if statements. Then have a another method private double FindTodaysPrice(int day,double basic)
{
if(day >= 1 && day <= 10)
return basic - .50;
else if(day >=11 && day <= 20)
return basic + 1.5;
else
return basic; // i have forgot the price differences
}
