Thread: when a while loop will stop ?

what is the condition for the while loop to be invalid ?

i think the following are the condition for invalid while loop.


1. while(false ) // bool false --> loop will stop


2. while(NULL) ----> loop will stop

3. while(0) ----->loop will stop

4. while('\0') -----> loop will stop.


i think there are many more conditions like above... so there are basically different rules.

is there any other condition which can make the while loop stop ?
