How an Infix to Postfix Calculator Works

An Infix to Postfix calculator is a tool that converts mathematical expressions from infix notation (commonly used by humans) to postfix notation (commonly used by machines for easy evaluation).

What Is Infix Notation?

Infix notation is the standard format where operators appear between operands. For example:

  • (A + B) * C
  • 5 * (3 + 2)

What Is Postfix Notation?

Postfix notation, or Reverse Polish Notation (RPN), places operators after operands, eliminating the need for parentheses. For example:

  • Infix: (A + B) * C
  • Postfix: A B + C *

How Does the Infix to Postfix Calculator Work?

  1. Initialization: The calculator initializes an empty stack to hold operators.
  2. Process Left to Right:
    • Operands are directly added to the result.
    • Operators are pushed onto the stack based on their precedence.
    • Parentheses are handled by pushing or popping from the stack.
  3. Finalization: After reading the input, the calculator pops any remaining operators from the stack into the result.

Example: Converting Infix to Postfix

Consider the expression (A + B) * C:

  1. Infix: (A + B) * C
  2. Postfix: A B + C *

Benefits of Using an Infix to Postfix Calculator

  • Simplified Evaluation: Postfix expressions are easier for machines to evaluate.
  • Faster Processing: Eliminates the need for parentheses, improving computation speed.
  • Error-Free: Reduces mistakes in complex expressions.
