基於C#解決OJ刷題之輸入輸出問題的總結（AKOJ1064-1071A+B問題彙總）

聲明：題目部分爲akoj題目，代碼爲本人AC代碼。

由於本人學校的oj支持各種環境，很正常的其中就包含了C#，然暑假在家較爲空閒，本着學習C#和複習算法的態度和目的，就又開始折騰起oj了。

題目部分是最基礎的A+B系列，來看看C#的輸入輸出是怎麼一回事吧

Description

Your task is to Calculate a + b.
Too easy?! Of course! I specially designed the problem for acm beginners.
You must have found that some problems have the same titles with this one, yes, all these problems were designed for the same aim.

Input

The input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line.

Output

For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.

Sample Input

1 5
10 20

Sample Output

6
30

namespace AK1064
{
    class Program
    {
        static void Main(string[] args)
        {
            string sb;
            while ((sb = Console.ReadLine()) != null)
            {
                string[] s = sb.Split();
                int x = int.Parse(s[0]), y = int.Parse(s[1]);
                Console.WriteLine(x + y);
            }
        }
    }
}

C#的輸入系統很噁心，只能一行一行讀，然後分離出裏面的數據，再轉換成你想要的類型，然後才能處理

Description

Your task is to Calculate a + b.

Input

Input contains an integer N in the first line, and then N lines follow. Each line consists of a pair of integers a and b, separated by a space, one pair of integers per line.

和前一個差不多吧，哈哈，本來這幾道題就差不多

Description

Your task is to Calculate the sum of some integers.

Input

Input contains multiple test cases. Each test case contains a integer N, and then N integers follow in the same line. A test case starting with 0 terminates the input and this test case is not to be processed.

Output

For each group of input integers you should output their sum in one line, and with one line of output for each line in input.

Sample Input

4 1 2 3 4
5 1 2 3 4 5
0

Sample Output

    class Program
    {
        static void Main(string[] args)
        {
            string sb;
            while ((sb = Console.ReadLine()) != null)
            {
                string[] s = sb.Split();
                int n = int.Parse(s[0]);
                if (n == 0) break;
                int sum = 0;
                for (int i = 1; i <= n; i++)
                    sum += int.Parse(s[i]);
                Console.WriteLine(sum);
            }
        }
    }
}

注意注意，這道題代碼一直RE，表示後面有一道和這就區別個輸入0結束，但是那道題AC了，這題我猜是輸入數據不是嚴格的在一行輸入的，那樣的話C#就根本沒法讀，反正我再看看，以後要是AC了，我就把這句話刪掉

OK，C#的寫法感覺如何？也都差不多吧，我感覺是這樣，和C++、Java都殊途同歸，區別就是一些小細節吧能用在刷題上的，在家沒書，C#後面的東西沒法去看，現在還在不斷學習中，加油！
