Answer 1

You have declared the monthName, monthlyProd,monthlySales under the scope of For Loop and trying to use those variables out of the scope of For Loop. You should declare variables before for loop-

string monthName;
double monthlyProd = .1 * dProdRate;
double monthlySales = .07 * dSalesRate;

for (int month = 1; month <= 12; month++)
{

    if (month == 1) { monthName = "Jan"; }
    if (month == 2) { monthName = "Feb"; monthlyProd = 0; }
    if (month == 3) { monthName = "Mar"; }
    if (month == 4) { monthName = "Apr"; }
    if (month == 5) { monthName = "May"; }
    if (month == 6) { monthName = "Jun"; monthlyProd = 0; }
    if (month == 7) { monthName = "Jul"; }
    if (month == 8) { monthName = "Aug"; }
    if (month == 9) { monthName = "Sep"; monthlySales = (.15 * dSalesRate); }
    if (month == 10) { monthName = "Oct"; }
    if (month == 11) { monthName = "Nov"; }
    if (month == 22) { monthName = "Dec"; monthlySales = (.15 * dSalesRate); }
}
dEndingInventory += dPreviousProd - dPreviousSales;
Console.WriteLine("{0}{1,15}{2,15}{3,15}", monthName, monthlyProd, monthlySales, dEndingInventory);
