Fre*_*red 5 c# math command-line percentage
我有这个程序,每个可能200分中取3分,然后应该得到平均值并显示百分比.但是当我输入数字时,我得到00.0作为答案.我能做错什么?
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
int Score1;
int Score2;
int Score3;
Console.Write("Enter your score (out of 200 possible) on the first test: ");
Score1 = int.Parse(Console.ReadLine());
Console.Write("Enter your score (out of 200 possible) on the second test: ");
Score2 = int.Parse(Console.ReadLine());
Console.Write("Enter your score (out of 200 possible on the third test: ");
Score3 = int.Parse(Console.ReadLine());
Console.WriteLine("\n");
float percent = (( Score1+ Score2+ Score3) / 600);
Console.WriteLine("Your percentage to date is: {0:00.0}", percent);
Console.ReadLine();
}
}
}

您将整数除以整数 - 即使您将结果分配给a,也总是使用整数运算float
.最简单的修复方法是使其中一个操作数浮动,例如
float percent = (Score1 + Score2 + Score3) / 600f;

请注意,这实际上不会给你一个百分比 - 它会给你一个介于0和1之间的数字(假设输入介于0和200之间).
要获得实际百分比,您需要乘以100 - 这相当于仅除以6:
float percent = (Score1 + Score2 + Score3) / 6f;
