Starting from the sequence of characters "if(net>0.0)total+=net*(1.0+tax/100.0);", the scanner composes a sequence of <a href="https://en.wikipedia.org/wiki/Lexical_analysis#token" class="extiw" title="en:Lexical analysis">tokens</a>, and categorizes each of them, e.g. as identifier, reserved word, number literal, or operator. The latter sequence is transformed by the parser into a <a href="https://en.wikipedia.org/wiki/abstract_syntax_tree" class="extiw" title="en:abstract syntax tree">syntax tree</a>, which is then treated by the remaining <a href="https://en.wikipedia.org/wiki/Compiler#Structure_of_a_compiler" class="extiw" title="en:Compiler">compiler phases</a>.
