This section is for all those NET exam aspirants who are looking out for a solution for UGC NET computer science papers. As a person who had taken the examination i have searched the internet incessantly for the solution of paper-II and paper-III of computer science. Since i could not find any solid help(or rather no help at all) in this regard, i had decided to write my own blog posting the solution for each and every paper as and when i complete it. I have posted the solution for paper-II of December 2008(and it was quite a task). Wherever i could, i have given explanation for the answers. If it is too lengthy or too simple, i have left it out. Enjoy your preparation for the NET exam.

I just have one word of advice for all NET aspirants...

"Focus on the journey, not the destination. Joy is found not in finishing an activity but in doing it.”

int x = 0;
while ( x < = 10)
if (++x%10==0)
(A). x = 1 (B). compilation error
(C ). x = 20 (D) none of the above
Ans:- C. For the while statement there is a for loop inside. For the for loop, there is one if condition, based on which there is a break statement. Since the value of x initially is 0, the while condition would be true and the for loop would start executing. The if statement condition would be checked, since ++x would become 1 and 1%10 is not equal to 0, break will not be executed. Since for is infinite x value will go on increasing. Once the value of x reaches 9, ++x would become 10 and 10%10==0 and so break would be executed. So control will come out of the innermost loop and would go to the outer loop. Sinc the value of x is 10, and since it is equal to 10, once again the for loop would start its execution. Once the value of x reaches 20, 20%10 will be equal to 0 and again break will be executed and control would go to the outer for loop. When the condition is checked for x<=10,it is false as the value of x is 20 and so it comes out of the while loop and the printf statement gets executed, printing the value of 20. Whew!!!!! 27.
