Скачать или смотреть Infix To Postfix Conversion using Stack || Data Structures And Algorithms

Hi friends... In this tutorial we discuss how to convert infix expression into postfix expression. Infix expressions are readable and solvable by humans. We can easily distinguish the order of operators, and also can use the parenthesis to solve that part first during solving mathematical expressions. The computer cannot differentiate the operators and parenthesis easily, that’s why postfix conversion is needed.

To convert infix expression to postfix expression, we will use the stack data structure. By scanning the infix expression from left to right, when we will get any operand, simply add them to the postfix form, and for the operator and parentheses, add them in the stack maintaining the precedence of them.

Note: Here we will consider only {+, −,∗,/, ^} operators, other operators are neglected.
