请帮助我使用VB.Net编写此问题的代码 [英] please help me in writing the codes for this question using VB.Net

问题描述

使用VB.Net编写程序代码，在用户输入-1之前，它会不断询问学生20个成绩.该程序应显示用户输入的成绩标记的总数并计算平均值.

write the program code using VB.Net that would keep on asking for 20 grade marks of students until the user enters -1. the program should display the total of the grade marks entered by the user and calculate the average.

推荐答案

一种方法是使用InputBox设置循环以获取用户输入.

读取每个条目的输入以测试-1或将条目放入数组.

输入所有值后，执行平均值.

在读取过程中，您将需要将字符串输入转换为数字值.

这应该是足够的线索，而不会给您一个答案，所有这些要素在询问之前都应该已经涵盖在您的课程中.

One method would be to setup a loop using InputBox to grab user input.

Read the input on each entry to test for the -1 or put the entry into an array.

Once all the values have been entered perform the average.

You will need to convert string input to a numeric value as part of the reading process.

That should be enough clues without giving you the answer on a plate, all these elements should have been covered already in your course before they are asking about them.
