Lexical Analysis (1 Viewer)

Could someone please explain to me this syntactical and lexical analysis concept? I am very confused :/

Lexical Analysis is all about breaking a piece of source code like

total = 10 + 5

into parts (tokens).

so in that example we have "total" as a variable, "=" as an assignment, "10" and "5" as literal integers and "+" as an arithmetic operator.

Syntactic Analysis turns the tokens generated in the lexical analysis stage and creates a tree which describes the code in a way the compiler can understand.
