Project ForgeMatch the following according to input (from the left column) to the compiler phase (in the right column) that processes it:
(P) Syntax tree (i) Code generator (Q) Character stream (ii) Syntax analyzer (R) Intermediate representation (iii) Semantic analyzer (S) Token stream (iv) Lexical analyzer
- AP→(ii), Q→(iii), R→(iv), S→(i)
- BP→(ii), Q→(i), R→(iii), S→(iv)
- P→(iii), Q→(iv), R→(i), S→(ii)
- DP→(i), Q→(iv), R→(ii), S→(iii)
Explanation
Compiler pipeline: character stream → lexical analyzer → token stream → syntax analyzer → syntax tree → semantic analyzer → intermediate representation → code generator. So the syntax tree is processed by the semantic analyzer (P→iii), the character stream by the lexical analyzer (Q→iv), the intermediate representation by the code generator (R→i), and the token stream by the syntax analyzer (S→ii).
