How do you find the enum count?

What is the default value of enum in C?

Each enumeration-constant in an enumerator-list names a value of the enumeration set. By default, the first enumeration-constant is associated with the value 0. The next enumeration-constant in the list is associated with the value of ( constant-expression + 1 ), unless you explicitly associate it with another value.

What is the size of enum class?

The size is four bytes because the enum is stored as an int . With only 12 values, you really only need 4 bits, but 32 bit machines process 32 bit quantities more efficiently than smaller quantities. The C standard specifies that enums are integers, but it does not specify the size.

Should I use enums?

When you need a predefined list of values which do represent some kind of numeric or textual data, you should use an enum. If you use enums instead of integers (or String codes), you increase compile-time checking and avoid errors from passing in invalid constants, and you document which values are legal to use.

What is the use of getproperties ()?

When you use GetProperties (), it returns a list of PropertyInfo objects. This gives you access the property’s definition (name, type, etc…) and allows you to get and modify its value.

Pass in the BindingFlags parameter to control what GetProperties () looks for. This is an enum flag, so you have to OR the options together. Filter the returned PropertyInfo objects by looking at its properties, such as PropertyInfo.PropertyType. By default, GetProperties () returns all public instance and static properties of a type.

How to get the property name of a property in Java?
