To be completed in 1 week Asignment 2Imagine the syntax of a programming language construct such aswhile-loop -while ( condition )beginstatement;:endwhere while, begin, end are keywords; condition can be a singlecomparision expression (such as x 20, etc.); and statementis the assignment to a location the result of a single arithmatic operation(eg., a = 10. b).Write a program that verifies whether the input follows the above syntax.Use flex to create the lexical analyser module and write a C programthat performs the required task using that lexical analyser.

Take a simple grammar, eg., expression grammar, compute the parsingtable entries by hand using the steps discussed in the class, and initializethe table in your program with these values. Try to parse input expressionsscanned by a lexical analyser (which can be easily created using flex). Theoutput of the parser should be SUCCESS or FAILURE depending on the input.
Incase of FAILURE the parser should indicate the incorrect token in the input. To be completed in 1 weekAssignment 6Modify your LR parser program of the preceding assignment such that alongwith the reduce actions, the parser invokes routines associated with theparticular grammar rule.
For example, for a reduction by the rule E - E + Tof the exression grammar, the parser computes the sum of the numberscorresponding to the symbols E and T on the RHS, and associates the sum tothe symbol E on the LHS.Hint: Observe that it will be necessary to associate values with differentsymbols in the stack. Whenever a reduce action is taken some symbols of thestack are to be replaced by a non-terminal symbol.
In this step the value tobe associated with the non-terminal is to be computed using the valuesassociated with the symbols that are being replaced.Assignment 7Take the C grammar from the book - The C Programming Language (by Kernighanand Ritchie), and try to generate a parser for the language using YACC.The notation for the grammar in the book is not strictly BNF (e.g. Use ofsubscript 'opt' with some symbols, use of 'one of', etc.), so some rewritingshall have to be done due to that. Apart from that there are are some LALRconflicts which you shall have to resolve by any appropriate means.Note: This exercise may require more time than available. So start the work,realise the issues and learn the tricks, so that completion of the remainingpart should depend not on learning time, but only on adequate coding time.
1.Include the nessary header files and d eclare the nessary variables. Define the key words and the identifiers with the constant and operator. Get the statement for analysis from the user. 4.Check each and every element in the statement with the defined keyword and if it matches print it as the keyword. 5.Check each and every element in the statement with the defined identifier and if it matches print the element as an identifier. 6.Check each and every element in the statement with the defined constant then find the equalance and print it as constant.
7.Check each and every element in the statement with the defined operator and if it matches print the element as an identifier. 8.Display every element on the screen as separated. 9.Exit the program.
