类的 值类型的返回？求大神解答。谢谢。

比如rnclass Arnrnpublic:rn A(int i):i(1)rnprivate:rn int i;rn;rnA fun()return A(1);rnrn这个函数到底返回的是什么东西。rn是一个类的成员变量？还是一个临时的对象？rnrn用A &a = fun()去接，这个明显是有问题的。rn而用connst A &a = fun() 去接的时候没有问题。rn也就是说它返回的是个常量。rn难道说局部的对象返回的也是局部常量对象？rn而常量对象又应该怎么解释？rn怎么说明里面有哪些东西？rnrn就像 int fun()rn int i = 1;rn teturn i;rn实际返回的是1这个常量。rnrn那么类返回的又是什么东西？ 求老手们解释解释一下。rn查了满多书，都没怎么讲这个东西，rn还是它们讲了，我忽略了？rn
