const_cast问题？
int main()
{
const int a = 1;
int *p = const_cast <int*> (&a);
*p = 2;

cout < <a < < endl;
cout < <*p < < endl;

cout < <&a < < endl;
cout < <p < < endl;
}

result:
1
2
0x1111
0x1111




[解决办法]
cout < <a < < endl;
004113F4 mov esi,esp
004113F6 mov eax,dword ptr [__imp_std::endl (4182A8h)]
004113FB push eax
004113FC mov edi,esp
004113FE push 1 // 看这里，编译器优化直接用 1 替换a了 ：）
