C++之引用

#include <iostream.h>using namespace std;int main(int argc, char *argv[]){int a = 1024;int &b = a;cout << "a =" << a << endl;cout << "b =" << b << endl;b = 1023;cout << "a =" << a << endl;cout << "b =" << b << endl;/*引用初始化必须是一个对象，不是值*///int &c = 10;//cout << "c =" << c << endl;const int d = 100;const int &e = d;/*非const引用不能绑定到const 对象*//*因为const对象是只读的，而对非const引用值的修改会修改原对象的值。*/     //int &f = d; cout << "e = " << e << endl; /*const 引用可以初始化为不同类型的对象或初始化为右值*/ int f =12; const int &g = 12; const  int &h = g + f;  cout << "g = " << g << endl; cout << "h = " << h << endl;   double  i = 3.14; const int &j = i; cout << "i = " << i << endl; cout << "j = " << j << endl;  return 0;}
