程序代码：#include <iostream>
using namespace std;
void main()
{
int va1=100,*pva1;
float vf1=1.0,*pvf1,*pvf2;
int*pva2=NULL;
cout<<"value of pva2 is "<<pva2<<endl;
pva1=&va1;
pvf1=pvf2=&vf1;
cout<<pva1<<"\t"<<&va1<<endl;
cout<<pvf1<<"\t"<<pvf2<<endl;
}
本人菜鸟。。。using namespace std;
void main()
{
int va1=100,*pva1;
float vf1=1.0,*pvf1,*pvf2;
int*pva2=NULL;
cout<<"value of pva2 is "<<pva2<<endl;
pva1=&va1;
pvf1=pvf2=&vf1;
cout<<pva1<<"\t"<<&va1<<endl;
cout<<pvf1<<"\t"<<pvf2<<endl;
}
上面的这个程序最终运行的结果是
value of pva2 is 00000000
0041FBF0 0041FBF0
0041FBD8 0041FBD8
可是书上的结果是
value of pva2 is 0x00000000
0x0012FF7C 0x0012FF7C
0x0012FF74 0x0012FF74
求教下这两组结果为何不同？
