I am just wondering if there is an easier way to calculate lines based on (enter key) \n. One one to do is to go trhough each char and find how many \n are there in the file. The statement i am using is:
while ( fgets( line, LINELEN, fp ) )
{ /* more input */
              total_lines++; /* count it */  
}

thanks

Carl,

There are arguably quicker ways but apart from breaking out into system calls (which is then immediately non-portable) I cant think of any easier ones. That doesnt mean that greg's idea is wrong!! You just need to be aware of its limitations.

Other methods will use essentially exactly the same process of counting the 'newline' codes, just in different forms.
