Explanation / Answer

Ans.1. Since income contains 3 elements, therefore years = 3

Ans.2. double total = 0;
   for (int i = 0; i < income.length; i++)
{
total += income[i];
}
   cout << "Total income: $" << total << endl;
cout << "End of Report" << endl;

Ans.3. Total income: $156000.75
End of Report

Ans.4. No, because the variable is declared within the scope of for loop. Once, the for loop gets executed, the index variable is no longer in the scope.
