Reverse Polish Notation

Reverse Polish Notation (RPN), also known as postfix notation, is a mathematical notation in which each operator follows its operands. This eliminates the need for parentheses to dictate operation precedence, making it especially well-suited for stack-based evaluation.

The reverse-polish-notation program reads and evaluates mathematical expressions written in RPN. It uses a stack-based algorithm to perform arithmetic operations and provides basic error handling for invalid input.

Compile the Program

To compile the source file and generate an executable (a.exe), use the following command:

g++ .\reverse-polish-notation.cpp

Run the Executable

Suppose we have the following RPN expression:

51 49 +

The corresponding infix expression is:

51 + 49 = 100

If you run the executable, you will get the following.

> ./a.exe
51
49
+
=
100
