The lexical analyzer takes ___ as input and produces a stream of___ as output. a) Source program, tokens b) Token, source program c) Either of the two d) None of the mentioned
Solution 1

The lexical analyzer, also known as the scanner, reads the source program as its input. It then breaks this input down into a series of tokens, which are the smallest meaningful units of the program. These tokens are then passed on to the next stage of the compiler, the syntax analyzer.
