BASIC INPUT/OUTPUT 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 flows 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 flows from main memory to a device like a display screen
