/*** Rule Section has three rules, first rule 
matches with capital letters, second rule
matches with any character except newline and 
third rule does not take input after the enter***/

// yywrap() - wraps the above rule section
/* yyin - takes the file pointer 
          which contains the input*/
/* yylex() - this is the main flex function
          which runs the Rule Section*/
// yytext is the text in the buffer

// to take input from file
// FILE *fp;
// char filename[50];
// printf("Enter the filename: \n");
// scanf("%s",filename);
// fp = fopen(filename,"r");
// yyin = fp;
