 Posted: Sun Sep 28, 2003 8:45 pm Post subject: reading from files with fstream |
 |
|
Here is the problem I am having. Right now i need to open a file and read
from it using fstream. I can do that. However, the file I am reading from
consists of two numbers at that top and then a series of other characters.
The other characters I can do with no problem however, I do not know how to
read the numbers as ints. I want to send them to integer variables. I have
been using the get(<variable name>) to extract the characters with no
problem. If somebody could help me I would be most appreciative. Thanks in
advance!!!

stream >> number;
It's much easier to help if you post your code.

It depends heavily on your file format, but in many cases you can just
do this:
ifstream_var >> int_var;
