使用C语言时，经常需要调用malloc()和free()函数来进行动态内存的分配和回收。有些时候，程序员可能会忘记回收分配的动态内存。为了解决这个问题，这里设计了一个代替malloc()和free()函数的数据结构（或者类）——ObjectManager。ObjectManager中提供了objmgr_malloc()和objmgr_free()以及objmgr_show_mem_info()函数。objmgr_malloc()函数负责按字节总数动态分配内存并且予以记录，objmgr_free()函数负责释放内存，objmgr_show_mem_info()可以供程序员随时查看动态内存分布情况。-The functions malloc() and free() are frequently used when we use the C language. Howerver, coders might forget to release the dynamic memory allocated via malloc() sometimes. I have designed the data structure(or a simple class)--ObjectManager in order to solve this problem. ObjectManager has provided 3 core functions objmgr_malloc() and objmgr_free() and objmgr_show_mem_info() to manage and display the dynamic memory. Here, objmgr_malloc() allocates dynamic by byte and keeps the related info as a record, objmgr_free() releases the dynamic memory and deletes the related record，while objmgr_show_mem_info() displays on the console the dynamic memory information.
