Question

您好，我是编码的初学者，我刚试过第一个项目。它是高尔夫的标准划痕分数。每当我运行代码时，它就会以完全错误的分数出现。这是代码：

import java.util.Scanner;

public class StandardScratch {
    public static void main(String[] args) {
        double Par1 = 0.0,
        Par2 = 0.0,
        Par3 = 0.0, 
        difficulty = 0.0;
        String operation;
        Scanner scannerObject = new Scanner(System.in);

        System.out.println("How many par 3 holes are there?");
        Par1 = scannerObject. nextDouble();

        System.out.println("How many par 4 holes are there?");
        Par2 = scannerObject. nextDouble(); 

        System.out.println("How many par 5 holes are there?");
        Par3 = scannerObject. nextDouble();

        System.out.println("What is the difficulty adjustment for the course?");
        difficulty = scannerObject. nextDouble();

        System.out.println("The Standard Scratch for the course is:" + ((Par1 * 6) + (Par2 * 4) + (Par3 * 5) - difficulty));    
    }   
}

当我尝试运行数字为6,10,2和-2的代码时，它的结果为88，而真正的分数应为66.谢谢！

你编码了这个：

height = 8        
ax.barh(yvalues-width/2, xvalues, height=height, color='blue', align='center')
ax.barh(yvalues+width/2, xvalues, height=height, color='red', align='center')

高尔夫球中3杆洞的划痕得分实际为3。

对变量使用误导性名称没有任何帮助。

如何制作标准划痕指南？
