Why You Should Almost Always Use Unsigned Integers in C and C++

Almost Always Unsigned

I argue that the fear of unsigned integers is misplaced, as most program values like array indices are never negative. While guides like the Google C++ Style Guide discourage them, I show how proper idioms handle underflow safely. Using unsigned types often prevents undefined behavior found in signed arithmetic, making code safer across languages like C, C++, Go, Rust, and Odin.

"The most typical argument against the use of unsigned integers is that it's more error prone since it's far easier for an expression to underflow than it is to overflow."
