Answer:

b. TRUE

Explanation:

Whenever they are passed as parameters to a function, the IO classes istream and ostream must be passed using a pass-by-reference parameter passing scheme.

This is because , assuming a pass by value semantics would require us to copy the value of the istream or ostream object which would be meaningless. In fact these objects don't even have a copy constructor at all. So such objects are always passed by reference.

The scanned documents should be saved as digital file (image or PDF format) in order to be sent. So, in order to send a portion of a map you should first convert the map into digital file and than simply send it through the fax modem. The best way to convert it to a digital file is to use an optical character recognition (OCR).
