.Answer is 4 : 01942 ( in octal value/code 0-7 characters would only be allowed ...but here we have 9 in between which is invalid )
many might think the ans is 2 : 0XFACE but the integer value of that is 64,206 ( its an hexadecimal code .......when converted into decimal gives the above value.....if the value is starting with 0X then it is hexadecimal code )
ans 2 is not coz you know why......it is a valid octa decimal code which consists of numbers only from 0-7..........

To all the ones who need an application explanation about call by value and call by reference just refer the page 136 of sumita arora text and see the 5.3 program which clearly differentiates between both ( by value and by reference ) .........just see that ...you would get a clear idea and conceptualising would be quite easy ( am not talking about the theory definitions.....) ............ |
