In this project, you will implement an

equation processor application using

linked stack and cursor array

equation processor interface will look like

the following:

The equation file is a special text file

that has a $\mathrm{.}242$ extension. The equations in

this file are in infix and$/$or postfix format. A

typical equation file looks like the following:
