Description: 编写C语言程序，模拟UNIX磁盘空间管理中使用的分组链接法。
1.定义一个记录磁盘块号的堆栈S—free[10]，以及记录栈中现有磁盘块数的变量S—nfree。
2.定义一个由40个元素构成的结构数组block[40]用作磁盘块存放。
struct size
{ int blocl[10]
}
struct blocd
{ struct size a[10]
//用于在空闲磁盘块号链中存放磁盘块号
}block[40]
3. 假设系统中文件的最大容量为100个磁盘块，且最多只有5个文件，定义一个由5个元素构成的结构数组file[5]用于记录各个文件占用的磁盘块，。
struct File
{ int fileblocd[100]
//用于记录分别分配给文件的磁盘块号
}file[5]
-Procedures for the preparation of C language to simulate the UNIX disk space used in the management of sub-link method. 1. The definition of a record number of disk blocks stack S-free [10], as well as the record of the existing disk block stack variable number of S-nfree. 2. The definition of a 40 element array structure consisting of block [40] for block storage disk. struct size (int blocl [10] ) struct blocd (struct size a [10] // used to free disk blocks in its store chain in its disk block) block [40] 3. the assumption that the system' s maximum capacity of paper disk blocks for the 100, and a maximum of only five documents, the definition of five elements of a structure consisting of an array of file [5] used to record all the disk blocks occupied by files,. struct File (int fileblocd [100] // used to record files were assigned to the disk block number) file [5]
