Question

please solve this give me output for this

Answer 1

Hi,

Please check screenshot for output:

Here I want to show you what actually is inside those varuables.

sum(0) = sum (0) + a (1)

sum (1) = sum (1) + a (3)

sum (4) = sum 4 + a (5)

sum (9) = sum (9) + a (7)

sum (16) = sum (16) + a (9); ( $a<=8 condition will fail here because a is greater than 8)

sum (16)

a (9)

Answer 2

output:
16
9
as you are get after the for loop there is no braces so only one statement run ...
$Sum=$Sum+$a..
and a values..
a=1
a=3
a=5
a=7
and for the value of a=9
the loop will not execute further so
$Sum=1+3+5+7
$Sum=16
$a=9
