    I have been asked a question ( an interesting one ) in an interview ystrday

    I was like given the following :


    if ( xxxxxxxxxxxxx)


    Now, the interviewer asked me not to change anything given except the " xxxxxxxxxxx"
    He asked me to write such a condition in place of xxxx such that we get the output as :

    if(!printf(hello")) will do the trick :)

    I don't think I would ever have guessed that.
    Once given the solution I would probably have commented something along the lines that I hope that question isn't indicative of programming standards within the company, cos if it was then I wouldn't want to work there anyway.

    Its known tht printf returns an int value and its no of characters it prints
    here printf("hello") will return 4
    and !4 is 0,so else part will be printed after hello
    so you get the reult....
    its cool na ...wat you say ravi

    yeah. superb solution dude!!

    so, this means the statement after the 'IF' is not getting printed.. but we are writing the same statement in the condition itslf.. . So, it has to get printed by default and itz directly jumping to else part..

    Cool !!

    a small careless error the return value is 5 not 4 :)
