What is ambiguity How is it removed?

If the grammar is not ambiguous, then it is called unambiguous. If the grammar has ambiguity, then it is not good for compiler construction. No method can automatically detect and remove the ambiguity, but we can remove ambiguity by re-writing the whole grammar without ambiguity.

Which keyword is used to remove ambiguity?

To solve this ambiguity scope resolution operator is used “::”. An example program is shown below to demonstrate the concept of ambiguity resolution in inheritance.

Can we remove ambiguity from context-free grammar?
