Answer:
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!
