Capabilities of CFG

There are the various capabilities of CFG:

Context free grammar is useful to describe most of the programming languages.
If the grammar is properly designed then an efficientparser can be constructed automatically.
Using the features of associatively & precedence information, suitable grammars for expressions can be constructed.
Context free grammar is capable of describing nested structures like: balanced parentheses, matching begin-end, corresponding if-then-else’s & so on.
