What is the Difference between Scanning and Parsing
What is the Difference between Scanning and Parsing The main difference between scanning and parsing is that scanning is the process of reading the source code one character at a time in a methodical manner to convert them into tokens while parsing is the process of taking the tokens and generating a parse tree as the output. Generally, a compiler is a software program that is capable of converting the source code into machine code so that the computer can execute that machine code. The compiler goes through multiple phases to compile a program. Scanning and parsing are two activities that occur during this compilation process. Overall, scanning occurs at the lexical analysis phase, whereas parsing occurs at the syntax analysis phase. Furthermore, the lexical analyzer performs scanning while the parser performs parsing.
