WebFeb 2, 2024 · The following table contains the following types: character, integer, Boolean, pointer, and handle. The character, integer, and Boolean types are common to most C compilers. Most of the pointer-type names begin with a prefix of P or LP. Handles refer to a resource that has been loaded into memory.

WebThe short answer is that it depends. When we say that a system is 32-bit, this could mean that the native integer is 32 bits wide, that the native address (i.e. pointer size) is 32 bits wide, or both. On top of that, not every architecture uses a flat memory model (for example, see x86 memory segmentation ). This further complicates matters.
