/**/ Preprocessor Macro Operator

The /**/ operator differs from the ## operator only in the way that the preprocessor treats white space between the operator and its arguments.

For example, the macro definition:

#define XY(x, y) x /**/y

does not give the same result as:

#define XY(x, y) x ##y

because the preprocessor preserves white space with the /**/ operator. With the ## operator, arguments are concatenated without white space.

The following examples demonstrate the use of the /**/ operator:

Invocation	Result of Macro Expansion
Sample Preprocessor Macro Definitions
`#define ws1(x, y) x //y#define ws2(x, y) x// y#define nws1(x, y) x ##y#define nws2(x, y) x##y`
`ws1(Turtle, neck)`	`Turtle neck`
`ws2(Turtle, neck)`	`Turtle neck`
`nws1(Turtle, neck)`	`Turtleneck`
`nws2(Turtle, neck)`	`Turtleneck`

For /**/ to function the same way as ## in ANSI/ISO C, there can be no spaces between the operator and the arguments.
