oop using c++  please give me full answer thanks Write a class Currency and makes the following attribute and member function. Currency name (String) Make a function name converter which converts the currency. Display function which display the value Make 3 derived classes name Dollar, euro and yen from Class Currency. In dollar class make a function converter and converts the minimum 50 dollars in rupees. In euro class make a function name converter which converts 1000 rupees into euro. User enter the amount less than 1000 display error message” invalid amount” Also create getter, setter and default constructor in above task.

Lab 27 Introduction to Functions Learning Objectives: Create functions in C++ Apply engineering problems to programming. Lab Materials: Computer with C++ and Visual Studio installed. Procedure: Create a new C++ file with the proper lab name. Wood moves (expands and contracts) with changes in humidity. Different species of wood react differently. Most wood movement is across the grain, not with the grain. As humidity increases, the wood absorbs moisture and expands. To calculate the wood movement: Delta-Width = width * change in moisture content * moisture co- efficient. Quartersawa Flatsawn Species Alder 0.0015 0.0026 Cherry 0.0013 0.0025 Red Oak 0.0016 0.0037 Black Walnut 0.0019 0.0027 Measurement is in inches. Write a that will ask the user for the change in moisture program content (expressed as a percent) and the width of the board. Display a menu that asks the user to choose a species and if it is flat or quartersawn Calculate and display the amount of wood movement as well as the…

- Create a struct called Complex for performing arithmetic with complex numbers. Write a driver program to test your struct. Complex numbers have the form: realPart + imaginaryPart * iwhere i is the square root of -1Use double variables to represent data of the struct. Provide a function that enables an object of this struct to be initialized when it is declared. The function should contain default values in case no initializers are provided. Also provide functions for each of the following:a) Addition of two Complex numbers: The real parts are added together and the imaginary parts are added together.b) Subtraction of two Complex numbers: The real part of the right operand is subtracted from the real part of the left operand and the imaginary part of the right operand is subtracted from the imaginary part of the left operand.c) Printing Complex numbers in the form (a, b) where a is the real part and b is the imaginary partSubmit one file which contains all code above: the structure…
