Implementation

Implement an ELF section header lister in C.

Requirements:

Define Elf64_Shdr structure
Read section headers from a simulated or real ELF file
Print section name, type, address, offset, size, and flags
Map common section types to human-readable names
Map common flags to readable descriptions
Show .text, .data, .bss, .symtab, .strtab sections
Handle the .shstrtab for resolving names

Test:

Show all section headers
Show correct types for .text, .data, .bss
Show flags (write, alloc, exec)

Why This Matters

`readelf -S` and `objdump -h` print exactly the table you are building here, and the GNU linker ld relies on sh_flags to decide which sections get merged, loaded, or discarded during linking. Reverse engineers scan section flags first when triaging an unfamiliar binary, since an executable .data section is a classic self-modifying-code or shellcode red flag.
