reading and writting data problem

Hello,
I am reading a data file but when I try to print what I already read,
it just prints the first line of the data correctly. From the second
line, it prints 0 for integers and nothing for characters. When I
tried to print the data after every line that I read, it prints
everything OK but when I try to pint after finishing the reading, it
just prints the first line correctly! For allocating the memory, I
used new and to free it, I used delete.
I have to add that sometimes everything goes OK and sometimes I am
facing this problem. Usually it depends how big the entry data is. Any
comments?

| Just a wild guess, but there might be a bug in your code. |
