Simple Linear Regression

So when we say that we have a pointer to some data, we really mean that we have the address at which the data is stored. But programmers don't usually set or examine these addresses directly. The exception to this rule are the developers of operating systems, device drivers, and embedded software, who sometimes need to set the value of a pointer explicitly in their code. Unfortunately, the exact representation of an address can change from processor to processor or can even be compiler dependent. This means that a physical address like 12345h might not be stored in exactly that form, or might even be stored differently by different compilers.[11] The issue that then arises is how a programmer can set the value of a pointer explicitly so that it points to the desired location in the memory map. Most C/C++ compilers for 80x86 processors use 32-bit pointers. However, the older processors don't have a simple linear 32-bit address space. For example, Intel's 80188EB processor has only a 20-bit address space. And, in addition, none of its internal registers can hold more than 16 bits ...»
