C Help

Honestly I dont :(
Which is why Im asking. Oh and I corrected the "/n" and switched it to "\". But yeah when I remove the entire else statement it works fine. I dont get it:(

That's because your brackets makes the compiler think it belongs to the FOR loop. That's why we use identation. See, it's very easy to see now that I intended it properly.

Thats interesting. I never honestly thought indentations had such a big impact on how the compiler looks at things. Ill go ahead and make the necessary adjustments so they match what u did, and see what happens.

But the reason why I never thought about is is because I have worked with Java and Scheme, and never really had a problem with indentations...

The compiler doesn't care about indentation - but YOU do. It makes it so much easier to read. You've basically put the else-statement in the wrong place, and it's very easy to see with proper indenting.

Alright well, lets see what happens...

Ok I see it!:)

This is one reason that Python is a very good language to start learning in - indentation is part of the "syntax" there, so if you write:

Code:

---

...
  if (x > y)
      print x
  print y

---

then print x is part of the if-statement, print y isn't, purely based on indentation. So to get the correct behaviour, you HAVE to indent correctly.

I honestly don't see it...

and I asked a friend of mine who has some experience with C and he doesnt see it either...

Code:

---

#include <stdio.h>

int main(int argc, char *argv[])
{

        FILE *fp;
        char arr[200];
        int filename;
        int numLines;
        const int MAX_LINES = 1;
    for (filename=1;filename<argc;filename++)
    {
            fp=fopen(argv[filename], "r");
            if (fp !=NULL)
            {
         
                    for(numLines=1;numLines<=MAX_LINES;numLines++)
                    {
               
                            fgets(arr,200,fp);
                            fputs(arr,stdout);
                    }
            }
         

    }
      else
        fprintf(stderr, "the file %s doesn't exist/n", argv[filename]);
 

           
}

---

I moved the else statement, but it gives me the same parse error. :(
So I guess Im stuck again...

I have a feeling Ill end up kicking myself cuz its something simple

Dude, already told you. Look above. Move the else after the IF.

Oh alright...sorry guess I missed that. Well I guess I learned a thing or two about this. As long as it makes me a better programmer I guess. Thanks alot guys.
