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 ( +, –, *, / ). Expre...

Example of Infix to Postfix Conversion Let's take an example to better understand the algorithm Infix Expression:A+(B*C-(D/E^F)*G)*H, where^is an exponential operator. Step by step output for infix to postfix conversion Input StringOutput StackOperator Stack ...

Output − Convert infix expression to postfix form. Begin initially push some special character say # into the stack for each character ch from infix expression, do if ch is alphanumeric character, then add ch to postfix expression else if ch = opening parenthesis (, then push ( into stack...

This is a simple program that converts infix expressions to postfix expressions. It is written in C and uses a stack to store the operators. It is a simple program that I wrote to show how to use a stack in C. cstackpostfixinfix-notationinfixpostfix-notationinfix-expressioninfix-to-postfix...
Prefix: An expression is called the prefix expression if the operator appears in the expression before the operands. Simply of the form (operator operand1 operand2). Example :*+AB-CD (Infix : (A+B) * (C-D) ) Given an Infix expression, convert it into a Prefix expression using two s...
