让我们继续深入的看 Test Test::operator + (const Test & Para1)。值得强调的是,无论如何temporary object是必须存在的,无数大师的经验证明,想用static member, dynamic memory等方法消除掉 temporary object 的 construction 和 destruction,都会产生这样或者那样的逻辑和程序错误。 但是我们仍然可以利用compiler来对...

In most cases, the order of evaluation for operands and function arguments is unspecified, meaning they may be evaluated in any order. Consider the following expression: a*b+c*d Copy We know from the precedence and associativity rules above that this expression will be grouped as if we had ...
