如何获得输出值 [英] How Can I Get The Output Value

问题描述

using System;
class pd
{
	public static void Main(String [] args)
	{
	long sum=1;
	long i=1;
		while(i<=1000)
		{
			sum=sum*2;
			i++;
		}
		Console.WriteLine(sum);
		pd1 ob=new pd1(sum);
		
	}
}
class pd1
{
	public pd1(long n)
	{
		long s=0,k;
		while(n!=0)
		{
			k=n%10;
			s+=k;
			n=n/10;
		}
		Console.WriteLine(s);
	}
	}

推荐答案

嗯。

那不是你的意思应该用于类。

所有这一切都是将代码从Main方法转移到类构造函数中并希望 - 它不是有效的OOP设计。



并且这忽略了它甚至不会起作用，因为long只有64位，并且不能容纳2 ¹⁰⁰⁰ - 最好 sum 将最终为零;在最坏的情况下，你会得到一个溢出的例外。



我建议你不要试图获得输出值，而是回到你的作业问题并重新读它：你几乎肯定会走错路。

Um.
That isn't what you are supposed to do with classes.
All that is doing is moving the code from the Main method into a class constructor and hoping - it isn't a valid OOPs design.

And that's ignoring that it won't even work, as a long has only 64 bits, and can't hold 2¹⁰⁰⁰ - at best sum will end up as zero; at worst you will get an overflow exception.

I'd suggest that instead of trying to "get the output value" you go back to your homework question and re-read it: you are almost certainly going down the wrong path.
