How to: Transform a Mathematical Expression from Infix Writing to Postfix Writing in C++

February 28, 2010 by Marius

Postfix writing (Reverse Polish Form) was made by Polish mathematician Jan Łukasiewicz. Particularities of this form of writing mathematical expressions are presented in […]. An algorithm for transforming a writing mathematical expressions from infix to postfix writing was developed by Edsger Dijkstra (Dijkstra Shunting Algorithm). Algorithm requires:

Postfix writing […] is a form of representation of mathematical expressions in which arithmetic operatorsare written specified by operands.Advantages of postfix writing over prefix and infix writing: Highlights clear policy of making operations; Brackets for forcing priority for implementing operators are not necessary; Evaluations are easily performed by computer. Algorithm for evaluation of an expression […]
