start symbol meaning in Hindi

Examples

1. (once again picking S as the start symbol ).
2. In the GCC ( GNU Compiler Collection ) this field is set by the linker based on the _ start symbol.
3. In the GNU Compiler Collection ( gcc ), the entry point used by the linker is the _ start symbol.
4. For example, assume the alphabet consists of a and b, with the start symbol S, and we have the following rules:
5. Such a grammar defines the formal language : all words consisting solely of terminal symbols which can be reached by a derivation from the start symbol.
6. The following example is given by : The unambiguous context-free grammar " G " over the alphabet { 0, 1 } has start symbol " S " and the following rules
7. A formal grammar provides an axiom schema for ( or " generates " ) a " formal language ", which is a ( usually infinite ) set of production rules to another sequence of symbols ( which initially contains just the start symbol ).
8. A grammar mainly consists of a set of rules for transforming strings . ( If it " only " consisted of these rules, it would be a semi-Thue system . ) To generate a string in the language, one begins with a string consisting of only a single " start symbol ".
9. Note that the grammar G = ( N, \ Sigma, P, S ) is effectively the semi-Thue system ( N \ cup \ Sigma, P ), rewriting strings in exactly the same way; the only difference is in that we distinguish specific " nonterminal " symbols, which must be rewritten in rewrite rules, and are only interested in rewritings from the designated start symbol S to strings without nonterminal symbols.
10. An "'unrestricted grammar "'is a formal grammar G = ( N, \ Sigma, P, S ), where N is a set of nonterminal symbols, \ Sigma is a set of terminal symbols, N and \ Sigma are disjoint ( actually, this is not strictly necessary since unrestricted grammars make no real distinction between the two; the designation exists purely so that one knows when to stop generating production rules of the form \ alpha \ to \ beta where \ alpha and \ beta are strings of symbols in N \ cup \ Sigma and \ alpha is not the empty string, and S \ in N is a specially designated start symbol.
