Neither the C nor C++ languages specify variable attenuators. In engineering, an "attenuator" is something that reduces the amplification of a signal or other source. The closest C or any other programming language would come to such an operation is through the negative "-", divide "/" or bitwise-right ">>" operators.
If this is in reference to a library which interacts with a physical mechanism through C, you will need to refer to the manual for the library's API for further information.
There are used to encapsulate a relationship between two or more variables.
The answer depends on whether or not the two variables are independent.
2^(n+1)
In the special case of two related variables (e.g., 2x - 7y + 5 = 0), the graph is a straight line.
External Variables are declared outside all functions, yet are available to all functions that care to use them. Features of external variables : Storage : Memory Default Initial value : zero Scope : Global Life : As long as program's execution does't come to an end
Static functions are tied to a class, not to a particular object. A static function can only access static variables because it has no knowledge of member variables.

You can copy them into global variables in the main() function, then have your other functions access those global variables. Global variables should generally be avoided, however.

None, except that they are functions of one or more variables.
