STANDARD LIBRARIES 


The C++ standard libraries provide an extensive set of 
input/output capabilities which we will see in 
subsequent chapters. This chapter will discuss 
very basic and most common I/O operations required 
for C++ programming. 

C++ I/O occurs in streams, which are sequences of bytes. 
If bytes flow from a device like a keyboard, a disk drive, 
or a network connection etc. to main memory, this is 
called input operation and if bytes flow from main memory 
to a device like a display screen, a printer, a disk drive, 
or a network connection, etc., this is called output operation.
