I've never seen it before. I thought it was a typo for "::sample", but when I saw it actually compiles I was very confused. Can anyone help me find out please? I don't think it's a goto label.
void f() { class: sample { // there were some members declared here } x; }

C mostly uses functional/structural programming instead of implementing Object Oriented Programming as in languages like C++ , Java , Python etc. which use classes .
The :: (scope resolution) operator is used to qualify hidden names so that you can still use them. You can use the unary scope operator if a namespace scope or global scope name is hidden by an explicit declaration of the same name in a block or class.
The main purpose of Objective-C programming language is to add object orientation to the C programming language and classes are the central feature of Objective-C that support object-oriented programming and are often called user-defined types.
In object-oriented programming , a class is a template definition of the method s and variable s in a particular kind of object . Thus, an object is a specific instance of a class; it contains real values instead of variables. The class is one of the defining ideas of object-oriented programming.
It is an unnamed class, and the colon means it inherits privately from sample. See it like
class Foo : private sample { // ... }; Foo x; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
