iteration 1
k=1
k!=5 is true
(k%2)!=0 is true
sum becomes 1
iteration 2
k=2
k!=5 is true
(k%2)!=0 is false
sum remains 1
iteration 3
k=3
k!=5 is true
(k%2)!=0 is true
sum becomes 1+3=4
iteration 4
k=4
k!=5 is true
(k%2)!=0 is false
sum remains 4
iteration 5
k=5
k!=5 is false
loop breaks
sum remains 4
0
k=0 (5 loop), k=1 ( 4 loop) ... calculate from 0 to 5, then k=5 loop breake.
