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-z or A-Z denotes operands and operators are ( +, –, *, / ). Expres...
Infix to Postfix Conversion in C: In this tutorial, we will learn how to convert Infix to Postfix using stack with the help of C program?ByAbhishek JainLast updated : April 13, 2023 Overview One of the applications of Stack is in the conversion of arithmetic expressions in high-level progr...

Input:(A+B)*C+(D-E)/F+G Output:AB+C*DE-F/+G+ Practice this problem The idea is to use thestack data structureto convert an infix expression to a postfix expression. The stack is used to reverse the order of operators in postfix expression. The stack is also used to hold operator...
