Questions tagged [uint]

is a type of variable and is used to store the equivalent of a mathematical non-negative integer

Due to the limited amount of memory a computer can handle, uint can represent just a subset of positive integers.

In C the uint standard is unsigned int and uses 4 bytes of memory (and thus can represents all integers int the range 0 to 4,294,967,295)
