Explanation / Answer

@@@ will be printed 12 times

(4 outer loop * 3 inner loop)

output is:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@

Each line will have @@@ printed 3 times because of inner for loop and println statement is fired after each inner for loop,

Hence 4 lines will be printed because of outer loop.

output is:

@@@@@@@@@

In Inner for loop after the set @@@ is printed, there is a println statement.

So 12 lines will be printed with @@@ on each line.

output is:

@@@

4. Question is empty.

Innermost for loop prints @ on each line.

Innermost for loop prints 3 lines.

Considering outer for loop and middle for loop , innermost for loop will be executed 6 times.

Total lines = 6 * 3 = 18 lines

output is:
