RE: What are enumerators? and what are in-line functions? giv ans with eg.
enum's are data type, while in-line functions are function. enum are integer repesentation in understandable form like- enum { monday, tuesday, ... ... sunday };
now if compare like if( 1== sunday) condition will return true.
in-line functions are the ones which get insert into the code where they are called. The difference between function and in-line function is no call will be made to the in-line function during execution. using this one can improve execution performance. this capability is compiler dependent and also depend on the optimization settings.

Enumerators: Enumerators are a way to give related constants a human understandable name for better code readability. For example:
We can use the following statement to check whether the connection to an SQL Server is open or not with the following statement
if(cnConnection.State ==1) { //Code to be executed when the connection is open }
However, the following code makes it more readable,
if(cnConnection.State ==ConnectionState.Open) { //Code to be executed when the connection is open }
Enumerators are declared in the following way (The syntax may differ from language to language):
public enum <enumName>{name1,name2,name3,...}
example:
public enum DAYS { Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday};
Inline Functions: Generally, during the execution of a program whenever a call to a function is encountered, the control switches from current execution to the method and vice versa. This impacts the overall performance of code execution. In order to remove this switching, Inline functions are used. It is made possible in the following way:
Whenever, the program gets compiled the inline functions get inserted at the calling location so that the execution does not switch in memory locations, and thus improving the program performance.
As already mentioned in the previous thread by Kamal, this is a compiler specific option.
Abstraction is defined as hiding details from the end user who should be in no way concerned about the details of the internal mechanism on implementation...but then the same can be achieved in C also

Anonymous Functions Anonymous functions can be created adhoc and used instead of a named function Although this can hinder readability when the function is more complex you can do this if you don t intend to reuse a function s code In the following example we pass such an anonymous function to Displ
Functions as Variables In JavaScript functions are first class objects This means that a function is regarded as a data type whose values can be saved in local variables passed as parameters and so on For example when defining a function you can assign it to a variable and then call the function thr
