This repository contains a C++ program that converts a mathematical expression from postfix notation (Reverse Polish Notation) to infix notation while maintaining the correct operator precedence.

In infix notation, we need parentheses to show which part of the expression to solve first. In postfix notation, the order of operations is already clear, so we don’t need parentheses.

Abstract: In Computer Science, Reverse Polish notation has simplified calculations and has benefited a new face to technology. Since 1960, RPN is used in calculators because its implementation is very ...
