![]() IF incoming SYMBOL is ‘)’ POP the stack and print OPERATORs till ‘(‘ is found.IF incoming SYMBOL is ‘(‘ PUSH it onto Stack. ![]() At the end of Expression, POP & print all OPERATORS from the stack.POP and print the TOP of stack, then push the incoming OPERATOR.IF incoming OPERATOR has EQUAL precedence with TOP of Stack, use ASSOCIATIVITY Rules.Then test the incoming operator against the NEW TOP of stack. IF incoming OPERATOR has LOWER precedence than the TOP of the Stack, then POP and print the TOP.IF incoming OPERATOR has HIGHER precedence than the TOP of the Stack, push it on stack.If OPERATOR arrives & Stack is empty, push this operator onto the stack.Rules for Infix to postfix using stack DS – Lastly we will write a C++ program to perform infix to postfix expression conversion. We will understand the Rules to convert an infix expression to postfix and also understand the pseudocode. In this tutorial we will convert in Infix Expression to a Postfix Expression using Stack Data structure.
