working with files and arrays

[Wessam Nabil]

hello

i have 2 arrays 1 to open files and 1 to delete it

but i have problem with the code

int a[8] = {11, 1, 3, 5, 17, 4, 2, 15};
int b[5] = {1, 2, 3, 4, 5};
int filehandle;

   for(int x=0; x<ArraySize(a); x++){
      string n = IntegerToString(a[x]);
      filehandle = FileOpen(n, FILE_WRITE|FILE_CSV);
      FileClose(StrToInteger("n"));
   }
   for(int y=0; y<ArraySize(b); y++){
      FileDelete(IntegerToString(b[y]));
   } 

the result should be 11, 17, 15 file name exist and the other files should be deleted

can anyone tell me whats wrong?

for(int x=0; x<ArraySize(a); x++){
      string n = IntegerToString(a[x]);
      filehandle = FileOpen(n, FILE_WRITE|FILE_CSV);
      FileClose(filehandle);
   }
   for(int y=0; y<ArraySize(b); y++){
      FileDelete(IntegerToString(b[y]));
   } 

StrToInteger("n") is wrong... you would need StrToInteger(n) to send the filename, but FileClose() needs filehandle not filename...

I suggest you read about the functions before using them...
