CMSC 330

Your final task is to make the following two modifications to the program:

• The program should accept input from a file, allowing for multiple expressions arranged one per line.
• All results should be changed from double to int. In particular the evaluate function should return an int.

You may assume that all input to the program is syntactically correct.

You are to submit the source code for the entire program and documentation (screenshots of successful run, test cases with screenshots, lessons learned) in a .zip file. Your program must compile with Microsoft Visual C++, or you may choose any other programming language of your choice.
