Prefix to Postfix Conversion 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) ) Postfix: An expression is called the postfix e...
Postfix to Infix Infix expression: The expression of the form a op b. When an operator is in-between every pair of operands. Postfix expression: The expression of the form a b op. When an operator is followed for every pair of operands. Input : abc++ Output : (a + (b + c)) Inpu...

The prefix decrement operator is similar to the prefix increment operator, except that the operand is decremented by one and the decremented result is used in the expression to get the value of the expression. In other words in postfix increment or decrement operation the In the postfix form, ...
Postfix expression (Reverse Polish Notation) An expression is said to be in postfix notation if the operators in the expression are placed after the operands on which the operator works. For example, abc*+ It’s the most used notation for evaluating arithmetic expressions Prefix expression (or ...
