Step 1
precision for A=0.81/(0.81+0.08+0.11)=1
precision for B=0.77/(0.10+0.77+0.13)=1
precision for C=0.74/(0.11+0.15+0.74)=1

- Follow the instructions from your instructor to accomplish the following in-class lab assignment. The Problem to Solve: The user needs a program to interact with employee records. The kinds of interactions are "Add an Employee" (Create record), "Show All Employees" (Read records), "View an Employee" (Read one record), "Update an Employee" (Update or change a record), and "Delete an Employee" (Delete a record). These interactions form the standard data processes in much of business software Create, Read, Update, and Delete, which are known by the acronym CRUD. The user needs to continue working with records until they are ready to tell the program. To do this, the program will present a menu of CRUD options and an option to Quit. The user will choose an option and the program will react accordingly. For this lab, the program will only print out which option the user chose. In later labs, we will add more functionality.

All variables, in another way of putting it, have not just a data type but also other qualities. To better describe the characteristics of each variable we encounter, please elaborate on the idea that will help us do so.arrow_forward
