We have given an Arithmetic Expression and we have to write a program that converts the infix to postfix using stack in C. The Expression will be given in the form of a string, where alphabetic characters i.e a-

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 using stack? I am using a vector as a stack here. ...
{ while (order(in[i]) <= order(s1.top())) { postfix += s1.top(); s1.pop(); } s1.push(in[i]); } } } return postfix; } int main() { string s; cout<< "Enter Infix: "<<endl; //cin>>s; s = "55+8"; cout << "infixToPostfix: "<<inToPost(s) <<endl; return ...
After traversing the entire string, remaining operators are popped from the stack and added to the postfix string. Example Usage of the infix_to_postfix Function Let's consider the algorithm's operation using the expression -2*ln(x)/(4*-2*sin(5*x)). Replacement of Unary Minuses: Original...
Prefix, Postfix, Infix Notation. Infix Notation To add A, B, we write A+B To multiply A, B, we write A*B The operators ('+' and '*') go in between. Stacks A stack is a linear data structure that can be accessed only at one of its ends for storing and ...
