问题：将10个不同的标记读入我的标记变量。 FOR循环

Question

import java.util.*; 

public class loops 

{ 

public static void main (String []args) 

    { 

     Scanner input = new Scanner (System.in).useDelimiter("\n"); 

     for (int i = 0; i <= 9; i++) 
     { 
        System.out.print("Enter your mark: "); 
        int marks = input.nextInt(); 
     } 

     int marks = + input.nextInt(); 
     int totalmarks = marks/10; 

     System.out.println("The class average was:"+ totalmarks + "."); 
    } 
} 

Answer 1

这个问题没有明确的问题，但根据我的解释，问题是添加所有输入标记并给出平均值，所以声明一个初始值为0的和变量，并添加所有标记作为输入并取平均值。

import java.util.*; 

public class loops 

{ 

public static void main (String []args) 

{ 

    Scanner input = new Scanner (System.in).useDelimiter("\n"); 
    int sum=0; 
    for (int i = 0; i <= 9; i++) 
    { 
       System.out.print("Enter your mark: "); 
       int marks = input.nextInt(); 
       sum=sum+marks; 
    } 


    int totalmarks = sum/10; 

    System.out.println("The class average was:"+ totalmarks + "."); 
} 
}
