12. Low-Level File I/O & Byte Buffers

Problem Objective

Write a function void hexDump(const unsigned char *buf, size_t len) that prints byte values in hex %02X format.

Expected Terminal OutputStandard Out

[*] ELF Magic Bytes: 7F 45 4C 46 02 01 01 00

[✓] Hex stream buffer verified (Time: 0.005s, Memory: 1.8 MB)

Execution Constraints

Implementation Checklist

Iterate buffer bytesPrint %02X for each byteAdd trailing newline
