How do i enter an EOF character in this program?

问题

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.

回答1:

To stimulate EOF in stdin,

• If you are on windows or DOS press CTRL+Z
• Or if you are running linux or some other OS, press CTRL+D

回答2:

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
