Introduction of Context-Free Grammar:

In TOC(Theory of Computation), CFG(Context Free Grammar) uses a set of recursive rules to generate patterns of string and it uses 4 tuples G={V, T, P, S}, where V is a finite set of non-terminal symbols, T is a finite set of terminal symbols, P is a set of production rules, and S is the start symbol.
