What is foo?

[satyam123]

can any body explain me about 'foo'.

[Banfa]

It is just a common name used in examples where an identifier is required (normally for a function) but there is no context in which to give the identifier a meaningful name.

Read all about foo and bar.

Sure. It is a metasyntactic variable. Just like bar, xyzzy, fee, fie, foe, fum, and a host of other arbitrary names that have no connotation to what type of value is stored in the variable's memory location.

For more info, see the Wikipedia article on metasyntactic variables.

Minor nitpick: xyzzy is not a metasyntactic variable; it's the secret password.

Sorry for the joke here, but I agree with JosaH , xyzzy is a cheat code in game ROADRASH.

I know, but it has taken on metasyntactic attributes in more recent history.

Oh, and anubhavit, it was a secret in "Colossal Cave Adventure" first.

I knew that game by the simple name 'Adventure'. We could play it simultaneously
with four people maximum on our PDP11/60 and then the machine went down ;-)
