I was creating a complex number class under a namespace called nmb
Here is the code:
namespace nmb // nmb stands for number
{
template<class T>
class complex
{
public:
// CONSTRUCTORS
explicit complex() { }
explicit complex(const T &imaginary, const T &real) : _imaginary(imaginary), _real(real) { }
explicit complex(const complex &_complex) { *this = _complex;}
// DESTRUCTOR
~complex() { } // useless, there aren't pointers, but for make it more clear
// METHODS
inline T real() const {return _real;}
inline T imaginary() const {return _imaginary;}
inline T complex_abs() const {return sqrt( pow(_imaginary,2) + pow(_real, 2)); } /* the absolute value of a complex num
is (a^2 + b^2)^1/2*/
// OPERATOR OVERLADING
inline bool operator==(const complex &Number) { return ((_imaginary==Number._imaginary) && (_real == Number._real));}
inline bool operator!=(const complex &Number) { return !(*this == Number); }
inline friend std::ostream & operator<<(std::ostream &os, const complex &Num)
{
return (os <<"(" << Num._imaginary << " , " << Num._real << ")");
}
inline friend std::istream & operator>>(std::istream &is, const complex &Num)
{
is >> Num._imaginary;
is >> Num._real;
return is;
}
private:
T _imaginary;
T _real;
};
}
Main.cpp
It is not finished yet, but in order to try it out I was going to create a simple main.cpp file and I wrote this program:
int main()
{
nmb::complex<double> a(2.4, 5.7);
nmb::complex<double> b;
//std::cin >> b;
std::cout << b << "\n";
return 0;
}
The problem is that if I leave this line //std::cin >> b; as it is, the code runs without errors.
Without the comment
However if I remove the comment
int main()
{
nmb::complex<double> a(2.4, 5.7);
nmb::complex<double> b;
std::cin >> b;
std::cout << b << "\n";
return 0;
}
the code throws many errors.
Errors
I leave here some of the errors because all the errors make me reach the 30000 characters limit
