Which phase of a waterfall approach is the person carrying out?ImplementationA programmer decides a program should convert U.S. units to metric units and decides to write the program in C++ using several functions. Which phase of a waterfall approach is occurring when the programmer starts writing the program?AnalysisA company has a new project it wishes to implement to track and analyze employee and customer interactions. The company leadership determines that the system should support direct data entry as well as automated data capture of phone calls and emails. Which phase of the waterfall process is occurring?ImplementationA programmer shows a program's first version to a customer. The customer provides feedback, which causes the programmer to change the goals of the program. In which phase of an agile approach are goals changed based on customer feedback?TestingA programmer shows a program's first version to a customer. Based on feedback, the programmer creates a second version, and then has a colleague run the second version on numerous inputs to ensure outputs are correct. Which phase of an agile approach is that colleague carrying out?ImplementationA programmer is currently programming the fourth version of a program. Each version has additional features to satisfy more customers. In which phase of an agile approach does the programming of the fourth version occur?System's classes, attributes, and methods and their features, constraints, and relationships Which elements are characteristic of a class diagram?Provides an overview of several use casesWhat does a use case diagram do?Include the libraryWhat does a programmer do first to use an existing programming library?Functions all relate to the same purpose.What relationship is common among a programming library's functions?The code has already been tested.What is an advantage of using a programming library?PythonWhich language is dynamically typed?
