Assume the existence of a File class with boolean data member, isValid, indicating the file is ready for I/O. Write a unary operator, !, that accepts a constant File reference, and returns true if the file is not ready for I/O and false otherwise.

The description for the given question is described in the explanation section below.

Explanation:

In reality, the "!" operator remains overloaded throughout the library of IO-stream, which effectively comes back the contrary feature of good.

It's how that they would load the "!" operator to construct a unary member overloading feature.

Example:

class abc

{

public :

bool isValid ( )    // return true

bool operator ! ( )    // return isValid( )

};

Optionally, to overwhelm the unary, you may build a global feature "!" user.

the printer can be used in a both wired and wireless network, only one of the connection methods can be used at one time when the wireless setting is enabled, the wired (ethernet) setting is disabled.

but first you need to

`connect the cord to your computer

`open settings app from the start menu

`click devices

`than click add printer or scanner

and than you should be able to do it from there, if not let me know i can you! : )

browsing like internet search? don't look at anything stupid. or set up restrictions on ur device's search engine. and if something suspicious comes up don't be dumb and click on it. i hope that's what ur question meant.
