how come siya??

Active member

see d diff. in ur answer n mine is only of 6 n 7 no.so i will tell u d reason.in 3rd line of d question,by ++arr[x++],d value of arr[2] is changed frm 6 to 7 bcoz of a prefix increment of d value of arr[2] on d whole.

hey guys the ans is :
15
7
8
10

1. output starts from 15 cause of ++i ( 'i' gets incremented before any sort of evaluation or execution)
2. the outputs dont not come in a row cause you've used the println statement which prints each output in a diff line

hey as_24!!!!!!check it on comp. d output is not ur answer yaar.i have checked it many times.u 2 check it!!!!!!!!!

Active member

hey!!!!! ne1.plz....check it n confirm

wotsay?

arre johny check it again.i have checked it 100 times n each time m gettin dis
2
15
7
8
10
n btw i have got d logic for my answer but cudnt get ne for urs.so plz. check it n confirm it....

Active member

hey!plz. ne body check dis n tell me d final answer!!i think johny sir has forgotten abt his prob. only

Active member

nono siya maam..i haven't 4gotten it...my bluej isn't working so i can't confirm it...

Active member

okk.. but m 100000000% dat my answer is correct.well nebody plllllz...confirm it...n johny u got a blueJ for ur comp. also in a pirated CD!!!!!!!!!!!!!!!!he he

Active member

arre babaa..pirated cdz ka bhoot sawar ho gya kya??mera toh bheja bhi pirated hai..hehee

Active member

hey...

i copy pasted this program...it is not working in my blueJ!!!!

Active member

int[]arr={2,4,6,8,10};
int x=1;
arr[x++]=++arr[x++]+arr[x++]:
for(int i=0;i<5;++i)
{
System.out.println(arr[i]);
}

i want to knw the correct solution...so, lets start step by step here itself, as this prog is not working in my blueJ!! Very Happy

x=1
so,
arr[x++]=arr[1]

++arr[x++]= ++arr[2] =++6=7 (am i right?)

+arr[x++]=arr[3]=8

so, the final answer is 7+8=15

is this right or wrong?

Active member

siya's right. i've also checked it

Active member

as_24...ok...but how is it done? i want explanation for the logic...i want to know how to solve it...thts y i asked whether my first step was right or wrong

btw...y doesnt it work in my blueJ? its giving: [ expected

Active member

hey anu see my previous post....dere i have xplained it!!

Active member

where yaar? i saw only ur answer...no explaination

Active member

here's the program:

int[]arr={2,4,6,8,10};
int x=1;
arr[x++]=++arr[x++]+arr[x++];
for(int i=0;i<5;++i)
{
System.out.println(arr[i]);
}

..and here's the working:

x=1
arr[1]=++arr[2]+arr[3];
=in subscript 1 of arr[] =7+8=15
thats the calculation.
++arr[2] increments the value in subscript 2 of arr[]. so 1 is added to 6 to get 7.
then under the 'for' construct values get printed on the output screen in order.so this is how the ouput goes:
2
15
7
8
10

frm where u got 2 in the first line?

i didnt understand Evil or Very Mad
