THIS PROGRAM MUST BE LIKE IN THE PHOTO I ASKED YOU 3 TIMES AND YOU DIDNT GIVE ME TRUE ANSWER. THIS PROGRAMS DO NOTHING PLEASE HELP ME AND ADD 3RD OPTION TO THE MENU WHICH IS SYMBOL TABLE. . PLEASE ANSWER IT CORRECT I WAS SO DISAPPOINTENT FOR YOUR ANSWERS. PLEASE DO IT CORRECT. PROGRAM MUST BE WRITTEN IN THE VISUAL STUDIO

The Task You will write a lexical analyzer in C++ or C# that recognizes integers, floating point numbers, identifiers, and relational operators <.>.-.--. Examples of integers are 34,-322, 0, Examples of floating point numbers are 3.243, 0.003, -3.4 ctc. (no exponent notation required, such as 3.2E4). Examples of identifiers are sum, x123, big_size, A12R etc. Your lexical analyzer function should read the input from a file, and return a result. The main program should first read the name of the input file, and enter a loop, with the following menu being displayed: Call lex0 - Exit "Exit" should end the program. "Call lexO" should call the lexical analyzer to get the next token, as well as additional information, such as a pointer to the symbol table entry, as necessary. Spaces should be skipped in the input file. Identifiers should be placed by lex) in the symbol table the first time they are encountered. In case an unrecognized string is found, lex0 should return UNKNOWN The TOKENS that should be returned by the lexical analyzer are: INTEGER FLOAT ID . GT (for>) LT (for) LE (for . GE (for EQ (for UNKNOWN x 45 5.4 33 size 345abc y1234> The lexical analyzer should return the following results: ID,0 INTEGER,45 These results should be printed on the screen in the main loop of the program each time lex) is called
