#include<iostream.h>
int main()
{
   int a=1;
const T1 a+a;
const T2 T1.T1;
cout<<"T2 is "<<T2<<endl;
return 0;
}
书上例题说运行结果是2，请问各位是如何运算得2的

#include<iostream.h>
int main()
{
   int a=1;
const T1 =a+a;
const T2 =T1*T1;
cout<<"T2 is "<<T2<<endl;
return 0;
}

我也不懂。。为什么是2啊。。请教各位高手

LZ，你买的书是盗版，我刚刚用程序调试，运行结果是4
