Why use an int if you plainly want a bool ?
why increment i in the middle, which makes the code harder to read ?
have you tried stepping through the code to see what values are being read into c and t ?

because this is only a part of the main programm, there is another thing that can change the value of a into 2.

You are right i should put it at the beginning

I am about to do it, maybe i should have done that before posting a message.
Thank you for your advise!

Where is the variable i initialized???

It´s initialisated at the beginning of the programme, i only quote the pertinent part of the programme.

From your replies, I think you need to do a line by line comparison. If so you may have to skip white spaces and blank lines.

It seems that space character isn´t considered as a character: i initiate i at 55 because i wanted to skip the first line (i know that i could use a pointer but i don´t know how it works) and the programme started to read from the 3rd line.
space isn´t considered as a character? I´ve read that it was part of the ASCII table.
Thank you all for your help and advise!

You should maybe try it with the getline () function, it reads spaces too. And then compare every position in your char set with the other one.
Or even better, if you are using VC++ use CString and the operator ==, CString::Compare () or CString::CompareNoCase ()

Thank you very much for your answer.
The fact is that i already have tryied to use getline() command. From a logical point of view, the programme is [to me] ok. But it doesn´t work. Therefore i get back to the command char.

What did you try?

I have tryed that:
c0..c3 and f01..f31 are declared as string (include < string >)<br />
<br />
getline(file1,c0);
getline(file1,c1); <br />
getline(file1,c2);<br />
getline(file1,c3);<br />
<br />
getline(file2,f01);
getline(file2,f11); <br />
getline(file2,f21);<br />
getline(file2,f31);<br />
<br />
if(f11==c1&&f21==c2&&f31==c3) <br />
{a1=1;}
But the thing is that i have to do that for 11 files. I think there is a problem with getline. I don´t know how to see the ´size´ of a line. Maybe the programme doesn´t considerer a line as a line in the text file.

From VC++ Help:
These functions extract data from an input stream as follows:
Variation Description
get();
Extracts a single character from the stream and returns it.
get( char*, int, char );
Extracts characters from the stream until either delim is found, the limit nCount is reached, or the end of file is reached. The characters are stored in the array followed by a null terminator.
get( char& );
Extracts a single character from the stream and stores it as specified by the reference argument.
get( streambuf&, char );
Gets characters from the stream and stores them in a streambuf object until the delimiter is found or the end of the file is reached. The ios::failbit flag is set if the streambuf output operation fails.
On the other hand...
istream& read( char* pch, int nCount );
istream& read( unsigned char* puch, int nCount );
istream& read( signed char* psch, int nCount );
Parameters
pch, puch, psch
A pointer to a character array.
nCount
The maximum number of characters to read.
Remarks
Extracts bytes from the stream until the limit nCount is reached or until the end of file is reached. The read function is useful for binary stream input.
Maybe one of this other options is better for you.

THANK YOU! 
That´s exactely what i needed! i am using dev c++ and i don´t have a help file about commands...

But you do use the online-Version of the MSDN[^], do you?
Failure is not an option - it's built right in.

If you are only interested in comparing the first 114 characters of the file, and you don't care what those differences are, why not just read that much of each file into a buffer and then compare the whole buffer using memcmp()?

because i don´t know this command and what a buffer is. In fact i did 30hours of programmation that´s all.

Sounds like you might need to get a refund.

 i would like that, but i did it at school... so it s hard to get a refund... Anyway i am not going to be a programmer. I am doing this programm to help a company that´s all.

Could you be a bit more clear with your query. Like are you developing an Application or this is the problem with some installed application. Is it MDI/SDI.
Please I request all posters to go through the Guideline Chris has posted at the first message in VC++ Forum. Please make use of it and get proper answers. We are here to help but to those who show some initiatives.

A much more verbose guideline can be found here. Folks would do well to read either.
