How to Use Enum with Functions in C++

In this C++ lesson, we combine enum with functions using a simple weekday menu example. What you’ll build: An enum EnWeekDay where values 1–7 represent Sunday to Saturday. A function readWeekDay() that reads a number from the user and returns an enum value. A function getWeekDayName(EnWeekDay weekday) that returns the name of the day as a string. A small menu in main() that shows 1–7 and prints the correct weekday name, or an error message for invalid input. You’ll learn: How to use enum as return types from functions. How to pass enum as parameters to functions. How switch case works nicely with enum to map values to text.
