C++的复制问题

keigopan

#include "stdio.h"
#include
class complex{
double re,im;
public:
complex(double r=0,double i=0):re(r),im(i){};
complex(complex &temp){re=temp.re+1;im=temp.im+1;} //1式
complex operator=(complex &temp){re=temp.re-1;im=temp.im-1;} //2式
void show()const{cout<<"re="< // complex(){re=0;im=0;}
//complex(double r=0,double i=0){re=r;im=i;}
};
int main(int argc, char *argv[])
{
double a=2.54;
int b=8;
complex mycomplex=9;
complex youcomplex(3,4.5);
complex shecomplex(a,b);
complex copycomplex=mycomplex; //该用1式还是2式初始
//化copycomplex呢？
getchar();
//system("AUSE";
return 0;
}
在VC下可以通过，可是到了DEV C++下就有了3个错误：
17 complex.cpp
initialization of non-const reference type `class complex &'
17 complex.cpp
from rvalue of type `complex'
7 complex.cpp
in passing argument 1 of `complex::complex(complex &'
到底那个实现了标准的C++呢？

我是不知道按标准该按1式还是2式初始化
