What is the output of the following program?
int sum = 0; int k = 1; int val = 1; for (k = 0; k < = 8; k++) { sum += val; val++; }
system. out. println(sum);

Output of the program is following

sum=45

Explanation:

The execution of the program in the "for" loop  will be following

For k=0

=> val=1 and sum=0+1=1

For k=1

=> val=2 and sum=1+2=3

For k=2

=> val=3 and sum=3+3=6

For k=3

=> val=4 and sum=6+4=10

For k=4

=> val 5 and sum=10+5=15

For k=5

=> val=6 and sum=15+6=21

For k=6

=> val =7 and sum=21+7=28

For k=7

=> val=8 and sum=28+8=36

For k=8

val=9 and sum=36+9=45

So all the iterations of for loop are completed and the output is 45.

I hope it will help you!

hi,

a perfect network would be right as you search something it would work in a snap, super protected, no hackers, would have maintenance every week, everyone one would share anything and everything as long as its safe, no viruses or over 18 stuff.communication would be like hangouts, and a network administrators would check what is happening and check if everything is safe.

hope this !

i do not get the question.
