complex 是你定义的一个类或者结构体的类型名 c代表这个类型的变量 &c是这个变量的引用 complex &c 的complex相当于int &a 中的int 前者的c相当于后者的a
只需证明\phi:f\mapsto \Delta f\\是满射(单射,保持运算显然) 对于\forall g\in S_{k+12},考虑h=\frac{g}{\Delta}\left\{\begin{array}{l}{V_{\infty}(g) \geqslant 1} \\ {V_{\infty}(\Delta)=1}\end{array} \Rightarrow V_{\infty}(h) \geqslant 0\right.\\所以,h\in \opera...

为什么不可以?你完全可以自己定义一个类试试啊。Complex c2=4.5 这样的语句表明了你的Complex构造函数肯定是带一个参数的,而且是float型。这样就可以在新建一个对象的时候,马上初始化Complex的参数。一点错误都没有
