1.
std::istream & operator>>(std::istream &is,complex_c &t) { std::cout<<"real: "; is>>t.x; std::cout<<"imaginary: "; is>>t.y; return is; }
如果参数 const complex_c & t, 就会无限死循环,,,好吧自己鱼就好。。const都不能改变类的值了还想去改变,,鱼
2.
complex_c::complex_c(double n,double m) { x= n; y= m; } complex_c complex_c::operator+(const complex_c &t)const { return complex_c(x+ t.x, y+ t.y); } complex_c complex_c::operator+(const complex_c &t)const { return (x+ t.x, y+ t.y); }
没加构造名则用逗号运算符 返回最右边结果y+ t.y,然后调用构造函数complex_c(y+ t.y,double m) m 在定义时给了默认值
