Q: What is the primary function of a lexical analyzer?
Solution: The lexical analyzer's primary function is to tokenize the input stream, breaking it down into meaningful symbols for further processing.
Steps: 5
Step 1: Understand that a lexical analyzer is a part of a computer program, often used in compilers.
Step 2: Know that the input stream is the text or code that the program needs to analyze.
Step 3: Learn that tokenization means breaking down the input into smaller pieces called tokens.
Step 4: Recognize that tokens are meaningful symbols, like keywords, operators, or identifiers in programming.
Step 5: Realize that the lexical analyzer takes the input stream and converts it into these tokens for easier processing by the next stage of the program.
