Sinossi

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In computer science, a pointer is a programming language data type whose value refers directly to (or points to") another value stored elsewhere in the computer memory using its address. For high-level programming languages, pointers effectively take the place of general purpose registers in low level languages such as assembly language or machine code—but, in contrast, occupies part of the available memory. A pointer references a location in memory, and obtaining the value at the location a pointer refers to is known as dereferencing the pointer. A pointer is a simple, less abstracted implementation of the more abstracted reference data type (although it is not as directly usable as a C++ reference). Several languages support some type of pointer, although some are more restricted than others."
