What is a symbol table?

Question

Can someone describe what a symbol table is within the context of C and C++?

Answer 1

Briefly, it is the mapping of the name you assign a variable to its address in memory, including metadata like type, scope, and size. It is used by the compiler.

That's in general, not just C[++]*. Technically, it doesn't always include direct memory address. It depends on what language, platform, etc. the compiler is targeting.
