while statement

[muser]

I have the following problem

do{

something;

while(temp1, != '\n');

compiler error: syntax error !=.

How can I write this code differently to accept the !=.


Also, and there is so many who have helpped in the past and know
exactly what I'm still working on.

How do I reset a file that is already been read, in effect once the
EOF has been reached, how would I be able to read the file over and
over again? Does the tellg function do this at all?

Get rid of the comma for a start.

Remove the ',' (comma):
while (temp1 != '\n');
Don't use commas unless you absolutely know what you are doing.
I rarely use them.

Once a file has reached EOF, it cannot be read again
_from_that_posi tion_. You have to clear the status and rewind or
relocate the file position:
ifstream myfile;
myfile.clear(); // Clear the EOF status.
myfile.seekg(0) ; // Set file position to beginning.

Get rid of the comma. Why did you put it there?

No, you need clear and seekg, in that order.

my_file.clear() ;
my_file.seekg(0 );
