Re: C code for LINE SEPARATING

I would make an array of strings, one element for each line. Than use something like getchar() to read in one character at a time until you find a '\n' (newline) character. Then start using the next element and read in the next line likewise until you reach the end of the file.

Re: C code for LINE SEPARATING

Have a look at a function calle3d fgets which is defined under stdio.h library. This function will do what excatly you want. It read a line of text from the text file until it EOF which then return NULL. The sample usage of that function can be found bellow

C Syntax (Toggle Plain Text)
FILE *fp;
char buffer[BUFSIZ];
 
if( ( fp = fopen( <filename>, "r") ) != NULL )
{
    while( fgets( buffer, BUFSIZ, fp) != NULL )
           printf( "%s", buffer );
           /* You could backup this buffer
              by copying it on to a different
              char array */
}
FILE *fp;
char buffer[BUFSIZ];

if( ( fp = fopen( <filename>, "r") ) != NULL )
{
    while( fgets( buffer, BUFSIZ, fp) != NULL )
           printf( "%s", buffer );
           /* You could backup this buffer
              by copying it on to a different
              char array */
}

Re: C code for LINE SEPARATING

the function that would be helpful for you here, i think, is STRTOK

in the string.h library.

it will separate any text into "tokens" based on a set of "delimiters"

your "tokens" will be individual lines, and your set of "delimiters" will simply be the newline character '\n'

once you have your individual lines you can insert anything you want in between them, and then rewrite them to a buffer or another text file as you desire.

Nope -- just use fgets() as previously suggested. No need to read the file one character at a time just to find line terminators because that's doing it the hard way.
