用char *malloc(unsigned size)函数向系统申请一次内存空间（如size=1000，单位为字节）， 用首次适应法 addr = (char *)fmalloc(unsigned size) 和 ffree(unsigned size,char * addr)或用循环首次适应法 addr = (char *)lmalloc(unsigned size) 和 lfree(unsi

-Char* malloc (unsigned size) function apply to the system once memory space (eg, size = 1000 bytes) for the first time to adapt to the law addr = (char*) fmalloc (unsigned size) and ffree (unsigned size, char* addr) or with a loop for the first time to adapt to France addr = (char*) lmalloc (unsigned size) and lfree (unsi
