Looking at the example code, I''m trying to make a few changes and have no clue how to do it. Basicaly, this is a CLI (Command Line Interface) Calculator. You punch in an equation and it spits out an answer. I''m trying to get it to store calculations as well as print them out in numerical order according to their result, like so:

2
+
1=
1+1+2=
4 * 4=
^D
2 + 1 = 3
1 + 1 + 2 = 4
4 * 4 = 16

Answers aren''t printed out until ^D (EOF) has been reached. I''m just having problems doing those last few things with the code I have. Any help is appreciated. Download example source: http://forums.extremeoverclocking.com/attachment.php?attachmentid=32848

I should also mention that support for multiple equations is needed...currently the program is only printing out the answer to one. Also, it is not requiring an equal symbol at the end of an equation but it needs to...

ie, if I run it now:
input:
5 + 5
output:
10

What I''m trying to do:
input:
5 + 5 =
1 + 4 =
7 * 2 =
output:
1 + 4 = 5
5 + 5 = 10
7 * 2 = 14

You''re gonna have to add each equation to some sort of list as you go along. Then sort it by the answer at the end before you output it. As for requiring an equals symbol, well, that''s a lot of files in that zip, and in a language most of us won''t understand. It might help if you were able to post the specific part that handles the input.
