- The following class starts to define a Complex number as two numeric (int or float) values, which specify the real and imaginary parts of the Complex number. For example, we can write x = Complex(1,2) to represent the complex number 1+2i (with real part 1 and imaginary part 2) and y = Complex (2,-3) to represent the complex number 2-3i (with real part 2 and imaginary part -3). In the Complex class below, overload(a) the method called by the repr function, producing the standard result (b) the method called by the str function: the correct sign (+ or -) must appear between the real and imaginary parts: for x and y above, str(x) returns '1+2i' and str(y) returns '2-3i'. For Complex(0,0) it returns '0+0i' (c) the addition operator: we can compute the sum of two complex numbers or the sum of a complex number and an int or float (these two types are pure real: each has 0 as its imaginary part) by adding the real parts of each and adding the imaginary parts; 2+3i plus 1+2i is 3+5i; likewise,…This is a debugging question - The files provided in the code editor to the right contain syntax and/or logic errors.

- How do I take a long number input, validate the input as a long number and then subsequently use it in a different class? Basically, I want to input and validate a 15-16 digit long number (to exclude string and float), fetch it again to validate it with a different set of conditions in a different or subsequent class.This is what I have so far 2. Too few parameters #include <stdio.h> Void simple(); Int main() { Int n; simple(1,2,3,4,5,6,7,8,9,10,11,12); Return0; } Void simple(int n){ printf(“%d”,n); printf(%d%d%d%d%d%d%d%d%d%d%d%d%d%d%d%d%d%d%d%d) } What gets printed? The values 1 and the garbage values get printed. Where do the values come from? The values are some random values generated for the storage part failures like this where we are not allocating values but using them. Why? 1 is printed as per the statement. Garbage values are generated because of not having any argument passed to them to locate a specific location. 3. Too small arraya) Design and implement a Comparable Java class to represent a Rational number such as3/2. Your class will have the following methods as well as any other methods necessary (setters, getters, etc.). - A constructor that takes all parameters (numerator, denominator), - A function that returns the number of existing Rational objects, - Override the tostring method, - Methods for adding and multiplying Rational objects, - Your methods will throw exceptions if there are problems. b) Write another class to test your Rational class including the exceptions.
