Learn and Master C Programming - enum' Data Types in C

This video tutorial introduces the ENUM data type in C, explaining how to declare and use it to define named constants. The instructor demonstrates setting up a project in Visual Studio, creating an ENUM for days of the week, and modifying default values. Best practices and examples are provided to enhance understanding.

What is the primary purpose of using ENUM data types in C?

• To manage memory allocation

• To define named integer constants

• To create arrays

• To define floating-point constants

How does the C++ compiler assign default values to ENUM members?

• All members are assigned the value 0

• Values are assigned in descending order

• Each member is assigned a unique random value

• Values start at 0 and increment by 1 for each subsequent member

Which of the following is a correct way to define an ENUM in C?

• enum days { Sunday, Monday, Tuesday };

• enum days = { Sunday, Monday, Tuesday };

• enum days { Sunday = 1, Monday = 2, Tuesday = 3 };

• enum days { Sunday: 0, Monday: 1, Tuesday: 2 };

What happens if you assign a specific value to an ENUM member?

• The ENUM becomes invalid

• All subsequent members are assigned the same value

• Subsequent members continue incrementing from the assigned value

• The assigned value is ignored

Which naming convention is sometimes used for ENUMs to indicate they are constants?

• Prefixing with 'C'

• Using lowercase letters

• Using numbers

• Prefixing with 'E' or using uppercase letters
