The first form (1) returns the format flags currently selected in the stream. The second form (2) sets new format flags for the stream, returning its former value. The format flags of a stream affect the way data is interpreted in certain input functions and how these are written by certain output functions.

The repeats tutorial focuses on flags that include repetition. You can use loops, such as for to perform the same action many times. Draw the flag of Bahrain, Qatar, India, Namibia and the European Union. Enums, Flags and Bitwise Operators in Unity3D (C#) (self.gamedev) Nice example that translates to C/C++ as well. However, sometimes flags aren't enough. Even the example given could be ineffective. Lets say you have an enum that defines various attributes. Option Index. GCC's command line options are indexed here without any initial '-' or '--'.Where an option has both positive and negative forms (such as -foption and -fno-option), relevant entries in the manual are indexed under the most appropriate form; it may sometimes be useful to look up both forms. Attributes are used for adding metadata, such as compiler instruction and other information such as comments, description, methods and classes to a program. The .Net Framework provides two types of attributes: the pre-defined attributes and custom built attributes. Specifying an Attribute. Syntax for specifying an attribute is as follows ? The documentation on Microsoft's flags enumerations is rather sketchy at best, but offers a more ideal solution for a great many problems. Visual C++ / C++ Create a flags enum by using the flags attribute and specifying values in the series. You can assign multiple flags values to a Use Enumerated Values with Bit Flags to Handle Multiple Options If your code uses a set of options and you don't use enumerated values, you can end up writing opaque code like this which passes an unexplained "magic number" to a method: Bit Fields / Flags Tutorial with Example - p
