爲什麼我的BMI平均代碼無法正常工作？

Question

我想計算一些人的平均BMI。當我運行此代碼時，每次單擊計算按鈕時，平均BMI都會下降。爲什麼？

float feet; 
float inches; 
float height; 
float weight; 
float bmi; 
float averagebmi; 

try 
{ 
    //Get user input. 
    feet = float.Parse(txtFeet.Text); 
    inches = float.Parse(txtInches.Text); 
    weight = float.Parse(txtWeight.Text); 

    //Calculations. 
    inches += feet * 12; 
    height = inches * (float)0.0254; 
    weight = weight * (float)0.453592; 
    bmi = weight/(height * height); 

    //Manager Calculations. 
    totalPeople += 1; 
    bmi += 1; 
    averagebmi = bmi/totalPeople; 

Answer 1

平均BMI應該是總BMI除以總人數。

您需要添加：

float totalbmi; 

那麼管理者的計算應該是：

//Manager Calculations. 
totalPeople += 1; 
totalbmi += bmi; 
averagebmi = totalbmi/totalPeople;
