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

I don't think the procedure is, but your formatting is pretty weird. There's nothing wrong with:

/* Eat spaces */
while ((c = getchar()) == ' ');

(that is, indicate there's intentionally not a body)
