"A constructor is a special member function that automatically initializes the objects of its class", support this statement with a program of all types of constructors. C++

Assignment: Class, Constructors, Destructors 1. Write a c++ program that uses <iostream> that has a class staff having fields: Staff_id , name, salary. Writea menu driven program for: 1) To accept the data2) To display the data3) To sort the data by name

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…
