我如何使用C＃

Question

这个正在开发的代码计算控制台应用程序平均的一个基本的应用程序，我需要的代码帮助制定出平均应该等于平均水平，显示3.00

// Define constrants and variables 
    // Constrants 
    int MAX_RESPONSE = 5; 
    int MIN_RESPONSE = 1; 
    int MAX_QUESTIONS = 50; 
    string scale5 = "5 - STRONGLY AGREE"; 
    string scale4 = "4 - AGREE"; 
    string scale3 = "3 - NEITHER AGREE NOT DISAGREE"; 
    string scale2 = "2 - DISAGREE"; 
    string scale1 = "1 - STRONGLY DISAGREE"; 
    string scale0 = "0 - UNABLE TO ANSWER"; 
    string Question = "Question : C# is better than C++. Do you\n"; 

     // Variables 
     int Response = 0; 
     int ValidResponseCount = 5; 
     int NonResponseCount = 2; 
     int QuestionCount = 7; 
     int MaximumResponse = MIN_RESPONSE; 
     int MinimumResponse = MAX_RESPONSE; 
     int TotalResponse = 1; 
     var AverageResponse = 0; 

     //calculate 
     AverageResponse = TotalResponse/ValidResponseCount; 


     // Output results 
     Console.WriteLine("SURVEY RECORDING SYSTEM "); 
     Console.WriteLine(Question + "\n" + 
      "\t" + scale5 + "\n" + 
      "\t" + scale4 + "\n" + 
      "\t" + scale3 + "\n" + 
      "\t" + scale2 + "\n" + 
      "\t" + scale1 + "\n" + 
      "\t" + scale0 + "\n\n"); 
     Console.WriteLine("response value"); 
     Console.WriteLine("RESULTS " + 
      "\n Number of valid responses  : " + ValidResponseCount + 
      "\n Number of non responses  : " + NonResponseCount + 
      "\n Number of times question asked: " + QuestionCount + 
      "\n Maximum response    : " + MaximumResponse + 
      "\n Minimum response    : " + MinimumResponse + 
      "\n Average response value  : " + AverageResponse); 

Answer 1

double AverageResponse = (double)TotalResponse/(double)ValidResponseCount; 

会这样做 - 因为您使用的是整数，所以/会返回一个整数并可能向上/向下舍入结果，投射到double会将此结果更改为有效的结果
