You forgot add '\0' in str so after str[3] = s[4]; you must add str[4] = '\0'; and you will get AC. Please after getting AC remove your code
Thanks a million, for that!
Now I got AC!
I really feel embarrassing abt what I had done!!! :-?

Just curious to know, what is ur machine type, OS and compiler?
My IDE is Code::Blocks and my default compiler is gcc and my OS is Windows XP but your bug doesn't depend on operating system or compiler:
It is important to preserve the NULL terminating character as it is how C defines and manages variable length strings. All the C standard library functions require this for successful operation
for more information you can try http://www.cs.cf.ac.uk/Dave/C/node19.html. So your code mabye work correctly or not

To saman_saadi,
You ask for code removing, but
you also have to remove the code from your "quote" on page one as well.
It's not automatically changed (not dynamically linked).

{
x +=40;
}
if(x==2400)
{
x = 0;
}
int tt = x;
i = 1;
while(tt!=0)
{
a[i++] = tt%10;
tt = tt/10;
}
for(j =1; j<=((i-1)/2);j++)
{
if(a[j]==a[i-j])
{
continue;
}
else
{
break;
}
}
if(j==((i+1)/2))
{
break;
