VC Teechart5 、Teechart8集合（带详细文档） 都是已经破解过的 使用过程中 发现 Teechart8版本比 Tee chart5 版本 多了平滑曲线。其他方面感觉两者差别不大。 个人工作这几年来看 VC中 Teechart 是目前功能最强大的曲线控件， 使用方法和中文函数文档里边都有，里面东西很多 ，亲测可用。

Requirements
1． Simulate a Unix file system on your Windows Platform
2． Understand the file system on Unix system, and the usage of i-nodes
3． Implement the function of sub-directory
4． The task needs to be completed using C++ or C
5．
Tasks/Functionalities
The following functions are required in your file system:
1． Allocate 16MB space in memory as the storage for your file system. The space is divided as
blocks with block size 1KB
Assume block address length is 32-bit;
Design the information contained in i-node
The i-node should support up to 10 direct block addresses
The i-node should support at least one indirect block address
2． The fist block is used for storing the i-node for the root directory(/). While your program is
lunched, two directories (/dir1 and / dir1/dir2) should be created, and also two files need to be
written as /dir1/file1 and /dir1/dir2/file2 (5 marks)
3． File 1 and 2 contain the message of “This is file 1.” and “This is file2”.
4． Following commands should be supported in your system：
a) Create a file：createFile fileName fileSize (10 marks)
i.e.：createFile /dir1/myFile 1024 (in bytes)
if fileSiz > max file size, print out an error message.
The file content is filled up with filename + repeated digits from 0 - 9
i.e.: “myFile012345678901234567890123….”
b) Delete a file：deleteFile filename (10 marks)
i.e.：deleteFile /dir1/myFile
c) Create a directory：createDir (5 marks)
i.e.：createDir /dir1/sub1
d) Delete a directory：deleteDir (5 marks)
i.e.: deleteDir /dir1/sub1 （The current working directory is not allowed to be
deleted）
e) Change current working direcotry：changeDir (5 marks)
i.e.: changeDir /dir2
f) List all the files and sub-directories under current working directory：dir (5 marks)
You also need to list at least two file attributes. (i.e. file size, time created, etc.)
g) Copy a file : cp (5 marks)
i.e.: file1 file2
h) Display the usage of storage space：sum (10 marks)
Display the usage of the 16MB
