Please help!!! Thanks in Advance Question: double [] amts = {43.34, 12.95, 9.36, 27.50, 10.20, 4.52, 63.25, 2.15, 8.97}; int i = 0; double total = 0; double average = 0; My Answer: double [] amounts = {43.34, 12.95, 9.36, 27.50, 10.20, 4.52, 63.25, 2.15, 8.97}; Array.Reverse(amounts); for ( i = 0; < amounts.Length; i++ Console.WriteLine("amounts [{0}] = {1}", i, amounts[i]; I also want to write a code that would print out the array in descending order..

I noticed you forgot parenthesis etc in the lines you showed. csharp double[] amounts = { 43.34, 12.95, 9.36, 27.50, 10.20, 4.52, 63.25, 2.15, 8.97 }; double sum = 0.0; // Sort the array and then reverse it into descending order Array.Sort(amounts); Array.Reverse(amounts); // Loop through the array for (int i = 0; i < amounts.Length; i++) { sum += amounts[i]; Console.WriteLine("amounts[{0}] = {1}", i, amounts[i]); } // Display the sum and average Console.WriteLine("Sum is: " + sum); Console.WriteLine("Average is: " + (sum / amounts.Length)); Enjoy!

Keep an eye on your syntax. I noticed you forgot parenthesis etc in the lines you showed.

csharp


double[] amounts = { 43.34, 12.95, 9.36, 27.50, 10.20, 4.52, 63.25, 2.15, 8.97 };
double sum = 0.0;

// Sort the array and then reverse it into descending order
Array.Sort(amounts);
Array.Reverse(amounts);

// Loop through the array
for (int i = 0; i < amounts.Length; i++) {
     sum += amounts[i];
     Console.WriteLine("amounts[{0}] = {1}", i, amounts[i]);
}

// Display the sum and average
Console.WriteLine("Sum is: " + sum);
Console.WriteLine("Average is: " + (sum / amounts.Length));
