輸入兩個數字，后一位數字是前兩位數字之和

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{
int i;
int a= Convert.ToInt32(Console.ReadLine());
int b= Convert.ToInt32(Console.ReadLine());
int c=0;
for (i = 0; i < 10; i++)
{
c = a + b;
a = b;
b = c;

}

Console.WriteLine(c);
Console.ReadLine();


}
}

阿拉怎麽會寫出伽傻的代碼來的，吐血死。

using System;
using System.Collections.Generic;
using System.Text;

namespace ConsoleApplication3
{
class Program
{
static void Main(string[] args)
{

hanshu sh;
sh = new hanshu();
sh.printhansu();
}
}

class hanshu
{
public void printhansu()
{

int i;
int a = Convert.ToInt32(Console.ReadLine());
int b = Convert.ToInt32(Console.ReadLine());
int c = 0;
for (i = 0; i < 10; i++)
{
c = a + b;
a = b;
b = c;

}

Console.WriteLine(c);
Console.ReadLine();
}
}


}
