This article delves into the sign extension problem encountered when printing hexadecimal values of characters in C. When using the printf function to output the hex representation of char variables, negative-valued characters (e.g., 0xC0, 0x80) may display unwanted 'ffffff' prefixes due to integer promotion and sign extension. The root cause—sign extension from signed char types in many systems—is thoroughly analyzed. Code examples demonstrate two effective solutions: bitmasking (ch & 0xff) and the hh length modifier (%hhx). Additionally, the article contrasts C's semantics with other languages like Rust, highlighting the importance of explicit conversions for type safety.
