Hello

How can I create a code-diff?
I will see the differences between two files:
-identic lines
-changed lines
-added lines
-deleted lines
I need an algorithm or a program code to do this


bye

I not sure exactly what your looking for.
You can use 'FC' from the command line to compare txt (code) files
usage FC file1 file2, use fc /? to get a full list of options

You use FC to compare two files
Just open the (dos) command prompt and type in FC FILENAME1 FILENAME2 and it returns the differences.

To compare two arrays of strings, you will have to write a function to do it. Are the arrays going to be fixed size single dimension or  multi dimension arrays or are they goin to be dynamic.

Thats my problem: how to write a function to compare the arrays.
I have two single dimension arrays, each array element for one line -> you can also create a "long" string with all elements of one array, and then compare the two strings.
I need a algorithm to compare..., within you can detect identic, deleted, added and changed lines.
