I have written a C++ program to convert an infix expression to postfix expression using recursion. I would like to know if it can be improved if possible. Can we improve it by not usingastack? I am using avectorvector<char>as a stack here. The following is my code: #include<iostream>...
Conversion to Postfix Form: If the expression is correct, the function do_postfix_convert is called for the actual conversion. char *do_postfix_convert(char const *const modified_infix) { Stack_int operator_stack; initStack_int(&operator_stack); int const length = strlen(modified_infix); char...
Convert infix to RPN with Latex names for operators Introduction I wanted a general infix to RPN convertor so I could use with \psplot in latex. I am using the Shunting yard algorithm. Using the code The fist thing I did was to modify the input string with. This removes all spaces ...
Using recursion to support repeated sequences of symbols has a certain appealingpurity, but it’s kind of a chore to make a separate named sub-rule each time we want to loop. So, we also use a postfix*to allow the previous symbol or group to be repeated zero or more times. crispiness...
ParseExpression: To convert an infix expression into an equivalent postfix expression. EVal: Which actually evaluates the postfix expression. This method internally makes a call to ParseExpression, if the expression is not already parsed. Like the tokenizer, the evaluator also makes use of the ...
Adding a white-space character after the - operator can lead to confusion for others.Separate binary operators by spaces. Infix expressions are OK to lineup on same column:F# Copy // ✔️ OK let function1 () = acc + (someFunction x.IngredientName x.Quantity) // ✔️ OK let ...
