Description

!!! 

It is very important to note that the OJ does not support file operations.
Please manually check whether your program’s output matches the five provided test cases.
After you finish writing your code, make sure to upload it to the OJ. I will download the latest submission for grading.

OJ無法支援file用法，請自行檢查給予的五筆測資和你程式的輸出有沒有相同，寫完後請務必上傳到OJ，我會抓最新的上傳下來批改

This program compares two text files line by line.

Each line contains at most m characters, and the filenames have a maximum length of n.

The program reads two filenames as input, then opens both files and compares their contents one line at a time.

• For every line number where the two files differ, the program outputs:

1. The line number.

• If the two files do not contain the same number of lines, the program must output:

1. The filename of the file with more lines.

2. The number of extra remaining lines in that file.

Line numbers start from 0.

Test File Content

Here are the test files. Please copy and paste them into NotePad and save them as files. Make sure the file names match the ones specified by the OJ exactly.

以下為程式所需比較的file原始內容，請複製貼上到記事本中並存檔，檔名必須要和OJ規範一模一樣。
