The substance of references in C + +

A C + + reference is the pointer has an address. Just optimize.

// ConsoleApplication4.cpp : 定义控制台应用程序的入口点。//#include "stdafx.h"int main(){    //char c = ‘a‘;    //printf("%c",(&c)[10]);    //上次没打印成功题    //以变量地址后数10个字节当成字符打印    //刚才忘说了..    /*    引用真的没有地址么    */    int Temp = 10;    int *p1 = &Temp;    int Temp2 = 20;    int &p2 = Temp2;    int *p = (&Temp2) -3;    printf("%d",*(int*)*p);    /*        int Temp = 10;013A17B8  mov         dword ptr [Temp],0Ah      int *p1 = &Temp;013A17BF  lea         eax,[Temp]  013A17C2  mov         dword ptr [p1],eax      int Temp2 = 20;013A17C5  mov         dword ptr [Temp2],14h      int &p2 = Temp2;013A17CC  lea         eax,[Temp2]  013A17CF  mov         dword ptr [p2],eax      */    /*    引用就是编译器做限制的指针    引动的地址对使用者是隐藏的    指针比较灵活,操作失误可能会产生严重后果,    C++推荐使用引用    */    return 0;}
