Use istream::getline.

You can try fgets which is C function look the sample code snippet FILE *fp = fopen("c:\\file.txt","r"); char ar[100]; while(fgets(ar,100,fp)) { print (ar); } fclose(fp);

If u can Dream... U can do it

And if you are using MFC, there's CStdioFile::ReadString().

yeah WhiteSky..I am developing a dialog based MFC application, in which i want to read a text file line by line for parsing and identifying certain charaters such as (), *. % etc. So i wanted to read the text file line by line to count occurance of each keyword at each line. Hope this information is sufficient.

well you can use of David answer CStdioFile::ReadString or CFile::Read :)

thanks very much...but i think CFile::Read reads the specified number of characters at one go. How do we know the size of each line well in advance. Is there any function in CFile that facilitates it?

I think this will work CStdioFile::ReadString :)

You don't (at least not without a lot of unnecessary code). That's why I suggested CStdioFile::ReadString() and not CFile::Read().
