Of course the symbol table must not have been stripped. So can the C program even locate its own symbol table, and is there a library interface for looking

I'm building a symbol table for a project I'm working on. I was wondering what peoples opinions are on the advantages and disadvantages of the various methods available for storing and creating a symbol table. I've done a fair bit of searching and the most commonly recommended are binary trees or linked lists or hash tables. What are the advantages and or disadvantages of all of the above? (working in c++) Your use case is presumably going to be "insert the data once (e.g., application startup) and then perform lots of reads but few if any extra insertions". Therefore you need to use an
