This is Mr. Fabio's code:

main(int argc, char *argv[])
{
   char *Array[];
   int length,i;
   char foo[10]="bar";
   length = strlen(foo) + atoi(argv[1]);
   Array = malloc(length)
   for(i=;i<length;i++)
       Array[i]="a";
}

Fabio, ur trying to create an array of char ptrs.....
so u  need to modify the way u mallocs space...
   Array = malloc(length)
is only applicable if u have defined Array
as char *Array;

(and u need to initialize "i" just in case... im not
sure about the default value of ints)
