Here is the code for conversion of infix to postfix using Stack in C. C++ #include <bits/stdc++.h> using namespace std; int precedence(char ch){ switch(ch){ case '-': case '+': return 1; case '*': case '/': return 2; default: return -1; } } bool isOperand(char ch){...

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. The following is my code: #include<iostream>#include<...
