For loop averaging

This cycle adds some conditions , Enter a student's N Our achievements , And finally print out the student's total score and average score .

1. thought ： use for A nested loop , First of all, the students' scores are uncertain , So first use for Loop in a i Define the number of subjects for the grade .

2. It should be noted that , Looking for the total score sum Or GPA   avg When , Be sure to define two variables to store the total score or average value , You can also write in the loop , But local variables and member variables are different （ This variable , Try to define it as a member variable , Prevent errors in subsequent operations .）

3. The result is for A cumulative process of a cycle , The average is the total score divided by the number of iterations , That is to say i.

See the following for the detailed code ：

package com.qfedu.test1;

import java.util.Scanner;

public class Test2 {
	public static void main(String args[]) {
		Scanner input = new Scanner(System.in);
		System.out.println(" Please enter the student's name ：");
		String name =input.next();
		int i= 1;
		int avg = 0;  // Define an average 
		int sum=0;    //  Define a total 
		for (i = 1; i <=5; i++) {
			System.out.println(" Please enter the first "+i+" Grades in the door grades ：");
			int score = input.nextInt();
			sum += score;         // Will result   Sum is assigned to the total number 
			 avg =sum/i;			// The average is the total / frequency 
		}
		System.out.println(name+" Hello! , Your average score is ："+avg);
	}
