WebFeb 26, 2024 · The range of an integer variable is determined by two factors: its size (in bits), and whether it is signed or not. By definition, an 8-bit signed integer has a range of -128 to 127. This means a signed integer can store any integer value between -128 and 127 (inclusive) safely. As an aside… 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.
