A general register is a register whose usage is determined by the programmer, not predefined as with dedicated registers such as the stack pointer. On an Intel CPU such as the 486 or Pentium, the 16-bit general registers are ax, bx, cx, dx, si, di, and bp; the 32-bit general registers are eax, ebx, ecx, edx, esi, edi, and ebp.

A get pointer holds the address of the next byte in the input area of an istream — that is, where the next byte will be retrieved if we use >> to read data from the stream.

Global scope describes the visibility of variables defined outside any function; such variables can be accessed by code in any function. It also describes the visibility of functions defined outside any class.

The global namespace is a name for the set of identifiers visible to all functions without a class or namespace name being specified. Adding identifiers to the global namespace should be avoided when possible, as such identifiers can conflict with other similar identifiers defined by other programmers.

A global function is a function that has global scope.

A global variable is a variable that has global scope.
