こんにちは、私たちは現在配列タスクを行っていますが、C＃を初めて使っています

Question

ユーザーが入力した5つの数値の平均と和を求めなければなりません。どんな助けもありがとう！これはこれまでの私のコードです： 基本的には、入力された数値の合計を補完する必要があります。また、後でコードに入力された数値を使用して配列を使用する方法については、「割り当てられていないintを宣言します。

{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      int numofnum; 
      int[] numbers = new int[numofnum]; 
      int index; 
      string avsu; 
      int average; 
      index = 0; 

      Console.WriteLine("Please enter the number of numbers you would like to find the average for, or add together: "); 
      numofnum = int.Parse(Console.ReadLine()); 


      Console.WriteLine("Would you like to find the average or sum of these numbers? (average/sum)"); 
      avsu = Console.ReadLine(); 


      if (avsu == "average") 
      { 


      do 
      { 
       Console.Write("Please enter Number to find the average of: " + index); 
       numbers[index] = int.Parse(Console.ReadLine()); 
       index = index + 1; 
      } while (index < numofnum); 

      index = 0; 

      do 
      { 
       Console.WriteLine("You entered the following values: "); 
       Console.WriteLine("Number " + index + ": " + numbers[index]); 
       index = index + 1; 

       Console.WriteLine("The average of these numbers is: " + (numbers[index]/2)); 
      } while (index < numofnum); 

       else if (avsu == "sum") 
      { 


      do 
      { 
       Console.Write("Please enter Number " + index + " to add: "); 
       numbers[index] = int.Parse(Console.ReadLine()); 
       index = index + 1; 
      } while (index < numofnum); 

      index = 0; 

      do 
      { 
       Console.WriteLine("You entered the following values: "); 
       Console.WriteLine("Number " + index + ": " + numbers[index]); 
       index = index + 1; 

       Console.WriteLine("The sim of these numbers is: " + (numbers[index])); // UNSURE HOW TO DISPLAY THE SUM!!!! 
      } while (index < numofnum); 
      Console.ReadLine(); 

      } 


     } 
    }

これは役に立ちますか？

static void Main(string[] args) 
{ 
    Console.WriteLine(
     "Please enter the number of numbers you would like to find the average for, or add together: "); 
    int numofnum = int.Parse(Console.ReadLine()); 
    int[] numbers = new int[numofnum]; 

    Console.WriteLine("Would you like to find the average or sum of these numbers? (average/sum)"); 
    var avsu = Console.ReadLine(); 
    var sum = 0; 

    if (avsu != "average" && avsu != "sum") 
    { 
     return; 
    } 

    for (var i = 0; i < numofnum; i++) 
    { 
     Console.Write("Please enter Number " + i + " to add: "); 
     numbers[i] = int.Parse(Console.ReadLine()); 
    } 

    for (var i = 0; i < numofnum; i++) 
    { 
     Console.WriteLine("You entered the following values: "); 
     Console.WriteLine("Number " + i + ": " + numbers[i]); 
    } 

    if (avsu == "sum") 
    { 
     sum = numbers.Sum(); 
     Console.WriteLine("The sim of these numbers is: " + sum); 
    } 

    if (avsu == "average") 
    { 
     var average = sum/numbers.Length; 
     Console.WriteLine("The average of these numbers is: " + average); 
    } 
}
