Can't read anything after sending EOF?

#include <stdio.h>
int main()
{
    char c = getchar(); //EOF (ctrl + d )
    while( ( c = getchar() ) != '?' )
    {
        printf( "%d\n", c == EOF );//infinite loop printing 1
    }
}

What happens here?

It is as if EOF completely blocks reading anything after it?

You need to call clearerr on stdin to clear the EOF. Also, note that getchar returns an int and not a char because EOF does not fit in a char.
