NTT Data Iteration, Recursion, Decision Quiz-1

Ans: do-while

Explanation:

do-while is especially useful when one processes a menu selection.

Answer: j is 0

Explanation:

First j=50. So, we will enter inside the while loop. J is not less than 10 hence j=j-10=40. Again we will check the while condition and we will enter inside the while loop. Now again since j is not less than 10 hence j=j-10=30. Similarly j=20,j=10. When j=10 we will check if the condition is false so we will do j=j-10. Hence j=0. Now we will check the condition and it will become true, so we will come out of the while loop. And we will print the value of j which is zero( 0).

Answer: continue

Explanation:

"continue" is used to go to the next iteration of the loop.

Answer: Infinite times

Explanation:

for loop will execute infinite times as there is no condition given.

Ans: Greater

Explanation:

(condition)? a:b

? operator will check the condition before it if it is true then it will print a otherwise b.

Hence, here a is greater than b then, "Greater" will get printed.

Ans: O(nlog(n))

Explanation:

The first for loop will run till n times. The second will run till log(i) times, i will run till n times. Hence complexity will be O(nlog(n)).

Ans: 4

Explanation:

The loop will ruin four times and give the below output:

0

3

6

9

So, the loop will run 4 times.

Ans:

Explanation:

We have i=1, we will print that for the next iteration i=1/1=1. Every time we are dividing i by i and i will remain 1. Hence we will get into an infinite loop. 

Answer: 5

Explanation:  

First iteration: 

i++ => i=1

if (i>max) => if(1>5), false so print i

1 gets printed

Second iteration: 

i++ => i=2

if (i>max) => if(2>5), false so print i

2 gets printed

Third iteration: 

i++ => i=3

if (i>max) => if(3>5), false so print i

3 gets printed

 

Fourth iteration: 

i++ => i=4

if (i>max) => if(4>5), false so print i

4 gets printed

Fifth iteration: 

i++ => i=5

if (i>max) => if(5>5), false so print i

5  gets printed

Sixth  iteration: 

i++ => i=6

if (i>max) => if(6>5), true

Hence we will come out of for loop.

Answer: 5 END

Explanation:

The program initializes two variables max and c to 5 and 0, respectively. It then enters a for-loop that runs while c is less than max. However, due to a semicolon placed after the loop, the loop body is empty, and the loop executes without any actions. After the loop, it prints the value of c (which is now 5) and "END" to the console. So, the output of the program is 5 END.
