Instructor note: Important Coding Guidelines: Use comments, and whitespaces around operators and assignments. Use line breaks and indent your code. Use naming conventions for variables, functions, methods, and more. This makes it easier to understand the code. Write simple code and do not over complicate the logic. Code exhibits simplicity when it’s well organized, logically minimal, and easily readable. A pedometer treats walking 1 step as walking 2.5 feet. Define a method named feetToSteps that takes a double as a parameter, representing the number of feet walked, and returns an integer that represents the number of steps walked. Then, write a main program that reads the number of feet walked as an input, calls method feetToSteps() with the input as an argument, and outputs the number of steps. Use floating-point arithmetic to perform the conversion. Ex: If the input is: 150.5 the output is: 60 The program must define and call a method:public static int feetToSteps(double…

Which ONE or MORE of the following, if any, ARE characteristics of Object-Oriented Programming? (you may select zero, one, or more than one choice) a. A class can be thought of as a category from which multiple "instances" or objects can be created. b. Flow of control is structured so that one function after another can manipulate data, which is available globally to all functions. c. Data and behaviors are grouped together in objects d. Object-Oriented Programming often results in "spaghetti code" that is hard to follow
