Problems with syntax c++

Question

I'm having problems with: (all line 34)

expected unqualified-id before "for"
expected constructor, destructor, or type conversion before '!=' token
expected ,' or;' before "for"
`i' was not declared in this scope

And i can't seem to find a solution, i've looked for sintax errors, but it seems fine to me. Any help appreciated. Thanks!

#include <cstdlib>
#include <iostream>
#include <fstream>
using namespace std;

int main(int arg[], int length)
{
    char c [3];
    char r [5];
    int i;
    for (i=0; i < 3; i++)
    {
    cout << "Inserisci i numeri delle colonne: (3 numeri) ";
    cin >> c[i];
    }
    for (i=0; i < 5; i++)
    {
    cout << "Inserisci i numeri delle righe: (5 numeri) ";
    cin >> r[i];
    }
    ofstream fout("DatiArray.txt");
    if(fout.is_open())
    {
    cout << "File aperto con successo!\n";
    }
    i=0;
     for(i=0; c[i] !='\0'; i++)
       {
       fout << c[i];
       } 
        cout << "Dati delle colonne scritti nel file DatiArray.txt con successo!\n";
        }

         for ( i=0; r[i] !='\0'; i++)  // this line 
        {
        fout << r[i];
        }
         cout << "Dati delle righe scritti nel file DatiArray.txt con successo!\n";
         }

 system ("PAUSE");    
}

Most modern text-editors have parentheses and brace matching, and most also have automatic indentation, use those tools. — Some programmer dude, Jan 05 '15 at 13:19
.. and then learn how to indent code manually, anyway. It's not difficult. — Lightness Races in Orbit, Jan 05 '15 at 13:20
Also, in the future please copy-paste the *actual* error log, unedited and complete. And please [read about how to ask good questions](http://stackoverflow.com/help/how-to-ask). — Some programmer dude, Jan 05 '15 at 13:20
I think you have 6 `{` and 8 `}`. You have 2 extra `}` after last two `cout`'s — Ashwani, Jan 05 '15 at 13:21
BTW, that is not one of the standard signatures for `main`... — David Rodríguez - dribeas, Jan 05 '15 at 13:21

Here:

 for(i=0; c[i] !='\0'; i++)
       {
       fout << c[i];
       } 
        cout << "Dati delle colonne scritti nel file DatiArray.txt con successo!\n";
        }

you have one closing bracket too many.

You have an excess } (and, again, later on in your program).

This would have been very easy to spot if you used any sort of rational code indentation scheme.

Your for loop is outside of your main.

Apart from what others pointed out, below are my observations.

char c [3];
for (i=0; i < 3; i++)

You are filling up the array till last element. And then,

 for(i=0; c[i] !='\0'; i++)

you are running loop to find null character which you not inserted as there was no space left for that charcter.

Did I say that? No. I said you are right, but that this is not the problem being asked about. – Lightness Races in Orbit Jan 05 '15 at 13:22
Well, I would say I didn't read question properly then...:) – ravi Jan 05 '15 at 13:26
