在程序运行的结果中应包含磁盘块的分配与回收操作。可根据输入的文件名、文件大小进行模拟磁盘分配，并在每次分配与回收后显示分配与回收是否成功，以及分配、回收的磁盘块号。在程序执行过程中，至少应包含分配不成功一次的信息。-The results of the program is running the disk blocks should be included in the distribution and recovery operations. According to the input file name, file size simulated disk allocation, and displayed after each allocation and recovery of the success of the distribution and recycling, as well as distribution, recovery of disk block number. In the program implementation process should include distribution of at least one unsuccessful information.
