Question

Define complex class in ruby and write methods and operations oncomplex objects

Answer 1

Answer:

Basically attr_accessor is a shortcut for when you need both attr_reader and attr_writer . It squashes down those two lines into one. Like so. class Person attr_accessor :name, :age, :sex, :email def initialize(name) @name = name end end.

Answer 2

Answer:

A method of the Complex class called Complex#*() returns the sum of two complex values.

Explanation:

Syntax: Complex.*()

Parameter: Complex values

Return: multiplicative product of two complex values.

Example:

# Ruby code for Complex.*() method

# declaring Complex value

a = Complex(200)

# declaring Complex value

b = Complex(-1, 4)

# declaring Complex value

c = Complex('i')

# Multiplication

puts "Complex * form : #{a*b}\n\n"

puts "Complex * form : #{b*c}\n\n"

puts "Complex * form : #{c*a}\n\n"

Output:

Complex * form : -200+800i

Complex * form : -4-1i

Complex * form : 0+200i

Ruby is the perfect language for object-oriented programming. Data abstraction, polymorphism, inheritance, data encapsulation, operator overloading, and other aspects are characteristics of an object-oriented programming language. Classes and objects play a key role in object-oriented programming. Ruby's classes and objects are its most crucial components. We may construct many different objects from a single class, just like class objects are simple to make. In Ruby, the new method produces objects. Member functions are referred to as methods in Ruby. The def keyword is followed by the method name to define each method. The method's name is always written in lowercase, and the end keyword marks the end of the method. Every class and function in Ruby ends with the end keyword.

Thus, a class serves as a template from which objects can be built. The object is also referred to as a class instance.
