What is the purpose of a symbol table in the context of lexical analysis?
Steps
Concepts
Step 1: Understand that a symbol table is like a list or a notebook where we write down important information.
Step 2: In programming, we often use variable names to store data, like 'age' or 'score'.
Step 3: When a program is being compiled, the compiler needs to remember these variable names.
Step 4: The symbol table keeps track of each variable name and what type of data it holds, like numbers or text.
Step 5: It also stores other details about the variables, such as their location in memory.
Step 6: This helps the compiler understand the program better and check for errors.
