Is using a while block to do nothing a bad thing?

Question

I\'m currently working through the excercises in \'The C Programming Language\'. Here\'s one of my solutions:

int c;

while ((c=getchar()) != EOF) {

if (c == \         


        

Answer 1

An alternative option which hasn't been mentioned yet:

while(condition)
    (void)0;

I really do not prefer to write my loops this way, but I had a TA last semester who did.
