While Loop is used in the loops where you do not have to know how many times to repeat the action(If you need to know), but need to know when to end loop.
I have not understood the clear meaning.
When do you practically use which loop. what are advantages and disadvantages, limitations of each loop. Do we use DO-While loop, i have not clearly see any benefit of it over WHILE loop except the it exceutes once. What practical benefit we get by executing atleast once.
Any links resources ideas highly appreciated. Thanks in advance
