We will use a stack data structure for the above conversion. The expression we want to convert can contain operators, operands and also brackets (' ('). We will consider all these while converting the expression. Rules for the conversion from infix to postfix …

It also supports trigonometric … WebWe can remove ambiguity in the expression without using parentheses by converting infix expressions to postfix expressions. Postfix expression. In a postfix expression, operators follow their operands. The postfix expression of A + B * C is A B C * +. For example, in the A (B C *) + expression, * follows its operands, B C. Say B * C evaluates to K. inbook citation latex
