Representation of memory in C++
This is a book on memory management. You, readers, are trying to figure out what it means, and I, as the author, am trying to convey what it means.
The way in which the standard describes memory can be seen in [wg21.link/basic.memobj]. Essentially, memory in C++ is expressed as one or more sequences of contiguous bytes. This opens up the possibility of memory expressed as a set of discontinuous blocks of contiguous memory because, historically, C++ has supported memories made of various distinct segments. Every byte in a C++ program has a unique address.
Memory in a C++ program is populated with various entities such as objects, functions, references, and so on. Managing memory efficiently requires grasping what these entities mean and how programs can make use of them.
The meaning of the word byte is important in C++. As detailed in [wg21.link/intro.memory], bytes are the fundamental storage unit in C++. The number of bits in a byte is implementation...
