浅析C++中memset,memcpy,strcpy的区别

代码如下:#include <stdio>#include <stdlib>#include <string>#include <assert>//memcpy：按字节复制原型：extern void* memcpy(void *dest,void *src,unsigned int count)//功能：由src所指内存区域复制count个字节到dest所指的内存区域；//同strcpyvoid *memcpy_su(void *dest, void *src, unsigned int count){       assert ((dest!=NULL)&&(src!=NU
