What does "unsigned integer" mean in programming?
unsigned integer is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
An integer type that stores only non-negative values (0 and above). Because no bit is needed for the sign, it doubles the positive range compared to a signed integer of the same size.
Example
"uint32_t size = 4294967295u; // max value for a 32-bit unsigned integer"
