如何将运行总数/计数器添加到 C# 控制台应用程序

Question

My application is taking user input (bowling scores) and averages them out. The issue I am coming to is the requirement of allowing the user to stop at any time. I placed 10 int variables and assumed one will not be calculating over 10. My question, is how do I keep a running total/ tally, so that if the user only inputs 2 scores to average, that I only divide by 2? Thanks for any help.

Console.WriteLine("Please input the score of game 1: ");
g1 = ReadLine();
game1 = int.Parse(g1);
Console.WriteLine("Would you like to add more scores? Press 'n' to continue to averaging, press any other key to continue!");
playagain = ReadLine();
if(playagain =="n")
{
    calculating(); 
}
Console.Clear();

This is how I coded the program. Do I create a variable, and assign itself inside of a while statement, to declare if any other buttons are pressed (program continues to another user input for game 2), to add 1 to the variable?

Answer 1

Use a List<int> collection to store the scores, then either

1) Divide the sum total of the values in the list and divide by the list's count property:

var scores = new List<int>();
int total = 0;

foreach(var score in scores)
{
  total += score;
}

var average = total / scores.Count;

2) Use LINQ's .Average() method to quickly get the average of all the values in the list:

var scores = new List<int>();
var average = scores.Average();

Naturally use any data types or conversions needed to obtain the level of accuracy you need/desire.

Answer 2

int count = 0; 
while(playagain != "n")
{
    Console.WriteLine("Please input the score of game 1: ");
    g1 = ReadLine();
    game1 += int.Parse(g1);
    count++;
    Console.WriteLine("Would you like to add more scores? Press 'n' to continue to averaging, press any other key to continue!");
    playagain = ReadLine();        
    Console.Clear();
}

the count variable will keep a running total on the number of inputs and the game1 variable will continue to add the scores up.

UPDATE for question asked;

class OtherClass{
   public int Counter {set; get;}
  .
  .//other logic
  .
}
OtherClass otherClass = new OtherClass();
int count = 0; 
while(playagain != "n")
{
    Console.WriteLine("Please input the score of game 1: ");
    g1 = ReadLine();
    game1 += int.Parse(g1);
    count++;
    Console.WriteLine("Would you like to add more scores? Press 'n' to continue to averaging, press any other key to continue!");
    playagain = ReadLine();        
    Console.Clear();
}
otherClass.Counter = count;

You can push into a list and use Sum() and Average() extensions. TO keep aceepting scores, you can use while loop

    Console.WriteLine("Please input the score of game 1: ");
    List<int> scores = new List<int>();
    int game1 = int.Parse(Console.ReadLine());
    scores.Add(game1);
    Console.WriteLine("Would you like to add more scores? Press 'n' to continue to averaging, press any other key to continue!");
    string playagain = Console.ReadLine();
    while(playagain != "n")
    {
        Console.WriteLine("Please input the score of next game: ");
        scores.Add(int.Parse(Console.ReadLine()));
        Console.WriteLine("Would you like to add more scores? Press 'n' to continue to averaging, press any other key to continue!");
        playagain = Console.ReadLine();
    }
    Console.WriteLine("Total is " + scores.Sum());
    Console.WriteLine("Average is " + scores.Average());
    Console.Clear();
