How do i enter an EOF character in this program?

Question

i was studying EOF character in c and came across a program :

#include <stdio.h>
main()
{
int c= 0;
while((c = getchar())!=EOF)
putchar(c);
}

its all good it is giving proper o/p but how do i come out of the loop by entering a EOF character which i entered and it did nothing.

If you are running this program on a linux terminal Cntrl+D should send EOF to the program. You can also use a pipe such as `echo "My Input" | ./program`. — R Sahu, Feb 07 '15 at 08:23

Under some environments, it is necessary to enter CTRL-Z twice. It is also usually best to precede the CTRL-Z (single or pair) or CTRL-D with the enter key, to avoid the last line of input being discarded. – Rob Feb 07 '15 at 09:21

I dont think there is an EOF character,and CTRL+Z and CTRL+D are used to inform the OS for termination. Follow these links it has the answers Representing EOF in C code? End of File (EOF) in C
