## Are ints negative?

An int is signed by default, meaning it can represent both positive and negative values. An unsigned is an integer that can never be negative. If you take an unsigned 0 and subtract 1 from it, the result wraps around, leaving a very large number (2^32-1 with the typical 32-bit integer size).
