reading k&r(c book) and confusing 1st chapter code [closed]
- by DarkEnergy
#include <stdio.h>
/* copy input to output; 2nd version*/
main()
{
int c;
while ((c = getchar()) != EOF)
putchar(c);
}
this is very confusing... since you never escape the while loop. I've learned that EOF is -1. i type -1 but it just reprints it. It's a never ending loop. Over time did the library get changed and differs from what the book intended it to be? when i say library i mean the putchar()/getchar() that's in the library... sorry.
