What does the term "empty loop" refer to exactly in C and C++?

Question

Is it this kind of thing:

for(;;)  {    statements;  } 

Or is it this:

for(initialisation;condition;updation) { } 

I am looking for answers with references to a variety of sources.

Answer 1

Your first case (for with empty expressions) is an infinite loop and the second one (with empty body of the for statement) is an empty loop

Answer 2

In my environment it is like this:

for(;;) { statements; } 

endless loop

for(initialisation;condition;updation) { }  

empty loop
