How can this if else statement be simplified?

I've got 25 options the user can take from 5 different choices.

I've tried using the "switch" function, but the "case" test one conditional at a time. I've tried looping, but I couldn't get my head round it.

Well, here is the "replace all" thing that I done in MS word to get it like this, phew!

I would really appreciate it if anyone can show me hints or suggestions to how this can be simplified:

Code:

        if ((chosenfile1==1)&&(chosenfile2==1)) statisticsof2textfilescompared ("The Sun","The Sun",".\\textfiles\\thesun.txt",".\\textfiles\\thesun.txt");
        else

Aiiiiiiiiiiiiiii. :o

There must be some way of making this simpler, there must bee....

Thanks in advance,
CookieMonster

char *cstring[4] = { "Harry Potter", ... };

statisticsof2textfilescompared(cstring[chosenfile1], cstring[chosenfile2]);

Use arrays of names.
e.g. {"The Sun", "The Times"}

Now you can access according to the chosen file
e.g. func(names[chosenfile1-1], names[chosenfile2-1]);

Whoa! Just like that!

Thank you! :)

This must be a very trivial question (sorry!) but what is the difference between doing

Code:

---

char *selectedname1[5]={"The Sun","Th...."}

---

and this

Code:

---

char selectedname1[5]={"The Sun","Th...."}

---

I understand that in the first code the array is being dereferenced, but what difference does this make compared to the second one? Am I not asking in the second code for the strings to be put into the array? :confused:

The first one creates an array of pointers that point to an array of characters.
The second one tries to store multiple arrays of characters into a single dimensional array.

I'll take that as a given rule. Thanks.
