我对编码很新，但是我在课堂上。我在这里需要帮助visual studio C＃ [英] I am very new to coding, but im in a class. I need help here visual studio C#
问题描述
基本上我已经制作了一个类似于刚开始的人的计算器，但我试图添加一些东西，所以它不仅仅是一个计算器。
我制作了计算器并且工作正常
但是在数字成倍增加之后我想得到一个符合正确数字的答案。
我想要的是将42（生命的意思，哈哈）作为这个计算器中的正确答案
所以当我fx乘以6 x 7它等于42我希望它去恭喜你，你已经找到了生命的意义
但是当答案大于42时，我应该稍微低一点，当然还要低于42高一点
我的代码：
我尝试过：
使用系统;
命名空间测试
{
class program
{
private static int num_2;
static void Main（string [] args）
{
{
int num_1;
int num_2;
Console.Write（写下你的第一个数字）;
num_1 =转换.ToInt32（Console.ReadLine（））;
Console.Write（写下你的第二个数字）;
num_2 = Convert.ToInt32（Console.ReadLine（）） ;
Console.WriteLine（Resultat：+ num_1 * num_2）;
Console.ReadLine（）;
int x = 42;
if（x == 42）
{
Console.WriteLine（正确，你已经找到生命的意义）;
}
else if（x> = 42）
{
Console.WriteLine（尝试稍微高一点）;
{
$ b $ Console.WriteLine（尝试低一点）;
}
Console.ReadLine（）;
}
}
}
}
Basically I have made a calculator like pretty much like anyone who is just starting out, but im trying to add something to it so its not just a calculator.
I made the calculator and it works fine
But after the numbers have been multiplied i would like an answer that goes with the right number.
What I want is to have 42 (the meaning of life, haha) to be the "correct" answer in this calculator
So when I fx multiply 6 x 7 and it equals 42 i want it to go "Congrats, you've found the meaning of life
But when the answer is greater than 42 i should go "a little lower" and of course less than 42 "a little higher"
my code:
What I have tried:
using System;
namespace Test
{
class Program
{
private static int num_2;
static void Main(string[] args)
{
{
int num_1;
int num_2;
Console.Write("write your first number ");
num_1 = Convert.ToInt32(Console.ReadLine());
Console.Write("Write your second number ");
num_2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Resultat: " + num_1 * num_2);
Console.ReadLine();
int x = 42;
if (x == 42)
{
Console.WriteLine("Correct, you've found the meaning of life");
}
else if (x >= 42)
{
Console.WriteLine("Try a little higher");
}
else if (x <= 42)
{
Console.WriteLine("Try a little lower");
}
Console.ReadLine();
}
}
}
}
推荐答案
你硬编码x为42，x需要是计算的结果
更改
You're hard-coding "x" to be 42, x needs to be the result of the calculation
Change
Console.WriteLine("Resultat: " + num_1 * num_2);
Console.ReadLine();
int x = 42;
to
to
int x = num_1 * num_2;
Console.WriteLine("Resultat: " + x.ToString());
Console.ReadLine();
好的，首先要注意的是当你执行
OK, the first thing to note is that when you execute
Console.ReadLine();控制台应用程序将停止，直到用户按下ENTER。因此，在 WriteLine 和 if 代码之间，在用户按下之前，您将看不到额外 ENTER - 没有提示他这样做！
The console app will "stop" until the user presses ENTER. So with that between your WriteLine and your if code, you won't see the "extras" until the user presses ENTER - which he isn't prompted to do!
Console.WriteLine("Resultat: " + num_1 * num_2);
Console.ReadLine(); <<<<<==== REMOVE THIS LINE
int x = 42;
if (x == 42)其次，您的代码专门将x设置为42：
Secondly, your code specifically sets x to 42:
int x = 42;因此它将始终针对相同的值进行测试！相反，将X设置为计算结果。
第三，如果在主 if 测试中测试相等性，则它无法匹配任何相等在 else 部分中 - 所以不要在 else 条件，使用<和>相反。
试试这个：
So it will always test against the same value! Set X to the result of the calculation instead.
Thirdly, if you test for equality in the main if test, then it cannot match any equality in the else parts - so don't test for "<=" or ">>=" in the else conditions, use "<" and ">" instead.
Try this:
int x = num_1 * num_2;
Console.WriteLine("Resultat: {0}", x );
if (x == 42)
{
Console.WriteLine("Correct, you've found the answer to life, the universe, and everything.");
}
else if (x < 42)
{
Console.WriteLine("Try a little higher.");
}
else
{
Console.WriteLine("Try a little lower.");
}
Console.ReadLine();
