I think output should be 20 16 12 8 4 0 -4 -8
exclude -12,coz -12 is less than -10
exclude -12,coz -12 is less than -10

(; ;) means that loop will run on the basis of conditional statement inside it.

Starting from 20,
i = i-4
i = 20-4=16,
i=16-4=12,
i=12-4=8,
i= 8-4=4,
i= 4-4=0,
i= 0-4=-4,
i= -4-4=-8,
i=-8-4=-12
So ,,,20,16,12,8,4,0,-4,-8,-12....
i = i-4
i = 20-4=16,
i=16-4=12,
i=12-4=8,
i= 8-4=4,
i= 4-4=0,
i= 0-4=-4,
i= -4-4=-8,
i=-8-4=-12
So ,,,20,16,12,8,4,0,-4,-8,-12....

This is use for infinity loop. it is use in server only.

ashok (;;) means there is no condition, it's of no use in that ,it will execute as long the if condition satisifes, then it will come out because of break statement.

i=20;
First print value of i(i.e: 20)
Check (i.e:20>=-10) true
Then value of i is 16 and print it(i.e., : i=20-4=16)
Then check as 16>=-10 true
Print 12(i=16-4)
Check 12>=-10 true
Print 8(i=12-4)
Check 8>=-10 true
Print 4(i=8-4)
Check 4>=-10 true
Print 0(i=4-4)
Check 0>=-10 true
Print -4(i=0-4)
Check -4>=-10 true
Print -8(i=-4-4)
Check -8>=-10 true
Print -12(i=-8-4)
Check -12>=-10
It is false
Then print the output as :20 16 12 8 4 0 -4 -8 -12

Print -4(i=0-4)
Check -4>=-10 true
Print -8(i=-4-4)
Check -8>=-10 true
Print -12(i=-8-4)
Check -12>=-10
It is false
Then print the output as :20 16 12 8 4 0 -4 -8 -12

-12 will also print because condition has been checked after print statement. That's why O/P will be 20 16 12 8 4 0 -4 -8 -12.
