CS 2500: Project 3 -- rpn calculator - again

Due Monday, November 7, 10:00 pm

For this project, you will develop a revised version of your rpn calculator Java program. This time, you will implement the stack class (stack of integers), using a different implementation. Implement the class in a second file, The only change to your main calculator class file should be in the name of the Stack class . . .

Implement the same rpn operations:

• + add the top two items
• * multiply the top two items
• - subtract the top item from the next item
• / integer divide the second item by the top item
• % find the integer remainder when dividing the second item by the top item
• m unary minus -- negate the top item
• r exchange the top two items
• d duplicate top item on stack
• p print (to the screen) the top item
• n print and remove the top item
• f print all the contents of the stack (leaving it intact)
• c clear the stack
• q quit
• h (or ?) print a help message

Submission: Use the CS homework submission system. Submit (at least) two files. Be sure to clearly identify yourself in the comments of your program (i.e., with your real name :-).

Input data: The input to the program will come from standard input. I will test your program with various examples

Scoring: The maximum possible score for the project will be 80 points. There will be up to 40 points for correct operation of your program, and up to 40 points for style, comments, etc.

Late programs will have their maximum possible score reduced to 0.9 times previous for each calendar day late (i.e., maximum possible score = 80 * (0.9^n) for n days late . . .).

Example: (the same as for project 2 . . .)
