hello everyone,
i executed this code but the loop never ends because i have no idea what EOF is hence the number of lines that i enter is not printed.
What do i press to signal EOF when i'm finish entering a suitable number of lines to see if they were counted by the program?(-1,0,1) do not work
not my code btwCode:#include <stdio.h> /* count lines in input */ main() { int c, nl; nl = 0; while ((c = getchar()) != EOF) if (c == '\n') ++nl; printf("%d\n", nl); }
