Explanation / Answer

q-1

starting value of j=4 and i=1

after that the update in j and i is made in seection x which is the point from where flow goes after it updates i indicated by x

and in every iteration(repetition of code) update is j=j+1 and i=i+2

first iteration: j=5 (// j=j+1 and j was 4 so j=4+1=5 )

i=3 (// i=i+2 and i was 1 so i= 1+2=3)

similarly second iteration : j=6 and i=5 (since last value of j and i were 5 and 3 respectively)

similarly other iterations:

third iteration: j=7 and i=7 (last values of j and i were 6 and 5 respectively)

fourth iteration: j=8 and i=9 (last values of j and i were 7 and 7 respectively)

now the fifth iteration for which it is asked the value of j and i just after execution j=j+1 i.e. values when i=i+2 is not executed

thus

fifth iteration : j=j+1 gives j=9 (since value of j was 8)

so answer becomes j=9 and i=9 just after execution of j=j+1 (ie. j is updated to new value but i is same as before, since i=i+2 is after j=j+1 so its still not executed. )

fifth iteration i=i+2 gives i=11 (since last value of i was 9)

sixth iteration: j=10 and i=13 (since last value of j and i were 9 and 11 respectively)

seventh iteration: j=11 and i=15 (since last value of j and i were 10 and 13 respectively)

eigth iteration: j=12 and i=17 (since last value of j and i were 11 and 15 respectively)

ninth iteration : j=13 and i=19 (since last value of j and i were 12 and 17 respectively)

now tenth iteration for which we have to tell the value of j and i after execution of i=i+1 ie both i and j are updated

tenth iteration: j=j+1 gives j=14(since last value of j was 13)

i=i+2 gives i=21(since last value of i was 19)

so the answer is j=14 and i=21 after 10th iteration ie. i=i+2 is executed 10th time both are updated since i=i+2 is after j has already been updated ie j=j+1 is already executed

Answers:

i) value of i and j after statement j=j+1 is executed for fifth time

i=9 and j=9

ii) value of i and j after statement i=i+2 is executed for tenth time

i=21 and j=14
