Webfor other types, appropriate literals are used (false, true, 0, 1, 0u, 1u, 0.0f, 1.0f, 0.0, 1.0f). Some additional accommodations are made for pre-C++11 dialects: false literal conversion to pointer is detected, instead of nullptr literal, 0 is proposed as replacement. WebTo force safe unsigned arithmetic, either add 0U or multiply by 1U as a no-op. For example: 0U + x + y or 1U * x * y. This ensures that the operands are promoted to at least int rank and still kept as unsigned. Divide/ remainder: Division by zero and remainder with a zero divisor are undefined behavior.
