C while loop only works if statement is true?

Question

I was looking at some kind of C code and I found this line.

if (temp==NULL)
    while (1) ;

From my understanding, when you get into an infinite loop, you do not exit if you do not break, how does it work? it breaks if the if statement is not NULL, if so, which forces it to check the if statement again and again?

Answer 6

It should be easier to understand that upon successful completion, ifit enters the while loop, iterating in a continuous loop,

if (temp==NULL){
  while (1) { }
}
