PLEASE DO IN C++ (Math: The Complex class)The description of this project is given in Programming Exercise 14.7 in the Chapter 14 Programming Exercise from the Book section. If you get a logical or runtime error, please refer https://liangcpp.pearsoncmg.com/faq.html. Design a class named Complex for representing complex numbers and the functions add, subtract, multiply, divide, abs for performing complex-number operations, and the toString function for returning a string representation for a complex number. The toString function returns a+bi as a string. If b is 0, it simply returns a. Provide three constructors Complex(a, b), Complex(a), and Complex(). Complex() creates a Complex object for number 0 and Complex(a) creates a Complex object with 0 for b. Also provide the getRealPart() and getImaginaryPart() functions for returning the real and imaginary part of the complex number, respectively. Overload the operators +, -, *, /, +=, -=, *=, /=, [], unary + and -, prefix ++ and --,…
In Haskell: Code a function "rangeProduct" that computes according to the following examples . Return 0 if the second argument is smaller than the first. What to do for negative numbers to do (if anything) is up to you. Write the program without recursion first and then write it with recursion. rangeProduct 3 5 --> 3*4*5 rangeProduct 5 3 --> 0 rangeProduct 6 12 --> 6*7*8*9*10*11*12 rangeProduct 4 4 --> 4
In C++ Just answer the questions in simple code please. Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms. Do this in a function called Sierra.

Haskell Print a array with array element from. 1 to 10
Overall Requirements: Use only Java features that have already been introduced in the course (e.g., loops, arrays, and functions but not objects). The functions must not mutate the argument array(s). You may assume that the array arguments to all functions are not null. All samples sent to standard audio must be between –1 and +1. Note that it is possible that the input samples to each method may not be between –1 and +1. The functions should operate as specified. While you should not play samples whose absolute value is greater than 1, it’s fine to manipulate such values along the way. However, to ensure that your final sample compiles with this requirement, you may want to implement one of the private helper methods: clamp() and normalize(), and then process your final sample before sending it to standard audio. You must not add public methods to the API; however, you may add private methods (which are accessible only in the class in which they are declared). Assignment: Audio…
