Hello,
I have following program that I got from the C book
The program is in a loop as you can see. But not sure how to enter the EOF character using my keyboard to terminate the prgram.Code:#include <stdio.h> main() { long nc; nc = 0; while (getchar() != EOF) ++nc; printf("%ld \n",nc); }
What is the actual character value of EOF. I know that integer value is -1.
ctrl+D might work, but I suggest you to use some other method for terminating the input
Obsession to networking and protocols made me cook up these:
NSN - Network Status Notifier
epb - Ethernet Packet Bombardier
T.H.O.N.G.S - Textmode Helper On Network Getting Sniffed
Nibbles - console UDP print listener/filter + something else
Feel free to try, comment and improve =)
EOF is not character entered (character values are 0-255) - it is return value indicating read error or end of stream eventOriginally Posted by webofunni
to emulate it from terminal - press Ctrl+D on linux or Ctrl+Z on Windows.
Another way - just redirect stdio to read from file like:
myprogram <myinput.txt
in this case the contents of the file will be sent to the myprogram stdio by the shell, when the whole file will be read getchar will return EOF
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

EOF is a macro which indicates the end of input.its value is -1 but it can be any of the negative integer.in windows press ctrl+z to terminate.
you can also use '\n' character to terminate your program.
