(Solved) : Assignment Re Going Extend Arithmetic Expression Tree Presented Class Handle Function Call Q29501085 . . . .

 

Would really appreciate some assistance.In this assignment were going to extend the arithmetic expression tree presented in class to handle function calls, with a single parameter. The grammar presented in class was simply exp -NUM expVAR exp-> ( exp ) expexp expexp 0P exp To extend this to functions, we add an additional rule exp -FNAME exp) The rules for function names are similar to those for variables, except that underscore - characters are allowed in function names but not in variable names. You should implement the functions vector<string tokenize(string s); exp* parse(vector<string>::iterator start, vector string>::iterator finish, int& prec);
