ambiguous grammar

基本解釋

You do not have to worry about backtracking and action side effects that may occur with an ambiguous grammar.
你不需要擔(dān)心一個(gè)模糊語(yǔ)法可能的回溯和動(dòng)作的副作用。
This grammar is ambiguous; yacc can't figure out what's going on.
該語(yǔ)法是不明確的；所以 yacc 無(wú)法指出接下來(lái)將做什么。
Some sentences have more than one structure, that is to say , these sentences are ambiguous. Context-free grammar can effectively express ambiguity, but it cann't resolve the ambiguity.
很多句子有一個(gè)以上的結(jié)構(gòu)，即這些句子是有歧義的，上下文無(wú)關(guān)語(yǔ)法可以有效地表示這種歧義，但是它沒(méi)有提供手段來(lái)消解歧義。
