编写一个C程序，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），用循环首次适应法



addr = (char *)lmalloc(unsigned size) 和



lfree(unsigned size,char * addr)模拟可变分区内存管理，实现对该内存区的分配和释放管理。-The preparation of a C program, using char* malloc (unsigned size) function to the system to apply for a memory space (eg, size = 1000, measured in bytes), with the first cycle to adapt to law addr = (char*) lmalloc (unsigned size) and lfree (unsigned size, char* addr) analog variable partition memory management, realize the memory allocation and release management.
