Questions & Step-by-Step Solutions
What does the term 'symbol table' refer to in a compiler?
Step 1: Understand that a compiler is a program that translates code from one programming language to another.
Step 2: Know that in programming, identifiers are names used for variables, functions, classes, etc.
Step 3: Realize that a symbol table is a special tool used by the compiler to keep track of these identifiers.
Step 4: Learn that the symbol table stores important information about each identifier, like what type it is (e.g., integer, string) and where it can be used (scope).
Step 5: Remember that the symbol table helps the compiler understand the code better and check for errors.
