课堂小练习: 设计、定义并实现Complex类

#include <iostream>
#include <cmath>
using namespace std;
class Complex{
public:
    Complex(double r=0.0,double i=0.0);
    Complex(float r2=0.0);
    Complex(Complex &c);
    void add(Complex c2 );
    void show();
    double mod();
private:
    double real,imaginary;
};
Complex::Complex(double r,double i):real(r),imaginary(i){    
}
Complex::Complex(Complex &c):real(c.real),imaginary(c.imaginary){
}
Complex::Complex(float r2):real(r2),imaginary(0){
}
void Complex::add(Complex c2){
    real=real+c2.real;
    imaginary=imaginary+c2.imaginary;
}
void Complex::show(){
    cout<<real<<"+"<<imaginary<<"i"<<endl;
}
double Complex::mod(){
    return sqrt(pow(real,2)+pow(imaginary,2));
}
int main(){
    Complex c1(3,5);
    Complex c2(4.5);
    Complex c3(c1);
    c1.add(c2);
    c1.show();
    cout<<c1.mod();
    return 0;
} 

总结：

1：在定义Complex(float r2=0.0);时 我用double就表明有错误，有点不明白？？？？
2：感觉框架不熟悉。
