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

However‚ we never considered the permanence of a variable or its scope i.e. the portion of the program where the variable is valid or recognized. All these factors are considered with storage classes. In C‚ variables differ in behavior from those in most of the other languages. A variable in C can have anyone of the four storage classes: 1. Automatic Storage class 2. External Storage class 3. Static Storage class 4. Register Storage class There are many ways in which a storage class

Research Question: How the amount of vitamin C in fruit juices affects its freshness and till what extent is the information provided on the pack by manufacturers is reliable? Background Information: Hypothesis: -fresh juices have more vitamin C than long-life -juice that is ‘not from concentrate’ is best in terms of vitamin content -if heat destroys vitamin C then heat-treated long-life juices will have lower concentrations -if heat destroys vitamin C then boiled fruit juice will have lower
