Hello CEans,

I am wondering and 😔, In CE we don't have a specific thread to have the discussions on CS Technical Interview Questions.

This thread is all about the CS interview questions. Any can post question here, irrespective of their department. In general, The interview questions are somewhat twisted like puzzles,so it will be interesting to solve those questions.

Expecting masterminds awesome answers and lightning questions:twisted:😁

PS:
After the question is answered here, also it is updated in the following thread

Ok tell this one,

1. We say current flows in wire, then when we give electricity to one end of cable, and other is kept in a tub, then the current should fall from that end is inside the tub? If yes, then why? If No, then why?

2. Who was the man who invented the famous A.C. motor?

3. Are we looking for any new system from electric transmission for long routes other than with cables?

4. What role does frequency plays in electric transmission?

Good Luck everyone. 😁
These are the easiest I could think. 😛

expecting very quick answers from Big K 😁

Answer is 'can't be compiled'

Why can't it be compiled??

I thought i+j+2 was the correct answer. At least. that's how it would work in C.

++i + ++j;

I do think this equals i+j+2; only..

PS : I dunno how this works n Java!!

Why can't it be compiled??
Because it was not ended with semicolon . All statements in java must end with semicolon. 😀

And yes regarding ++i + ++j - you are right it is equivalent to i+j+2[as per Java also 😀] . I considered it wrong in hurry as ++i + j++
