← Logic & PuzzlesWhat happens to computational complexity when a compiler uses a formal grammar to parse a source code file?
A)Complexity becomes exponentially unpredictable
B)Parsing complexity is formally constrained✓
C)Complexity is wholly computationally irrelevant
D)File size alone determines complexity
💡 Explanation
Formal grammars define precise rules, so a compiler uses the 'parsing algorithm' mechanism, limiting the complexity within defined boundaries, because the grammar dictates the allowed structures; therefore, parsing complexity is constrained, rather than becoming unpredictable due to the formal definitions in the grammar.
