    fgets() atumatically reads the next line
    use something like
    Code:
    while (fgets(..) != NULL) {
    ...
    }

    Don't think in terms of 'lines', think of a file as a long string of characters. You read one character and automatically move ahead to the next one, it just so happens that one character means a line break ('\n').
    p.s. What the alphabet would look like without q and r.

    Hi

    Thanx for the reply , but what im actually looking to do is read 1 line of text , display it on the screen , press a key and then the next line of text will be displayed and so on until the EOF is reached.

    mmm i wonder if im going about this the wrong way.
    And To All Those Opposed, WELL !!!

    Something like this I suppose:
    Code:
    int main(void)
    {
        /* Open the file */
    
        while (fgets(line, sizeof (line), file))
        {
            fputs(line, stdout);
    
            printf("Continue? (y/n)");
            fflush(stdout);
    
            if (tolower(getchar()) != 'y')
                break;
        }
    
        return 0;
    }
    p.s. What the alphabet would look like without q and r.
