Question

I got this assignment where I have linked list with Complex numbers and the task is to imput and print these numbers with help of linked list. Several years ago i studied the basics of complex numbers but the assignment is really confusing for me now and I don’t know where to start, the only given information is the one above and the following .h file:

#ifndef COMPLEX_H
#define COMPLEX_H
#include <iostream>
struct Complex
{
  int real, imag;
};
void read(Complex &, std::istream &);
void print(const Complex &, std::ostream & os=std::cout);
bool operator<(const Complex & lhs, const Complex & rhs);
bool operator>(const Complex & lhs, const Complex & rhs);
bool operator==(const Complex & lhs, const Complex & rhs);

#endif

I would be rally thankful for some initial guidance with this assignment, what should the print and read functons contain (except the given arguments) in order to use?? bool operators above? I googled for couple of hours but could not find any good relevance between complex numbers tutorials and my task, furthermore i have deadline for this and contacting my teachers with questions about this will take days.

Answer 1

The print function should display the number on the indicated output stream. Conventionally, complex numbers are displayed like this: 1+2i or this: (1+2i) or even this: (1,2). You might accomplish this through operator chaining:

os << "(" << c.real << "+" << c.imag << "i)";

The equality check should return true if both components of lhs are equal to their counterparts in rhs:

return lhs.real == rhs.real && lhs.imag == rhs.imag;

The details of read, operator< and operator> will vary according to your exact assignment. Re-read your assignment, paying close attention to any definition of what those functions are required to do.
