ok
this is ther code im using to find out if words entered to string 1 are a palindrome.
radar is a palindrome.
mom is a palindrome.
Basically a palindrome is a word that can be spelled backwards and forwards and still be the same word
Please help
this project is due this friday
Cmon man, a palindrome test is done in basic CS classes. Don't be a lamer. :P
It's a for loop that compares the final index to the first index, incrementing the first index and decrementing the last index. When they are within 2 of each other, you are done (the string is a palindrome), or if they are not and they don't match, you break out of the loop, and it is not a palindrome.

}
I'm a newbie to C++, but wouldn't that raise an error. I didn't think you could compare character arrays like that.
strcmp?

Aww Mynd, don't be mean. 90% of people start with lame things like
"Hello, World!\n"This is just the next step in a chain of lame beginning projects. Gotta crawl before you can walk... Or something like that...
bool palindrome(const char *str, int len) { return len < 2 || *str == len[str] && palindrome(str + 1, len - 2) ; }
bool palindrome(const char *p) { for(char *q = p + strlen(p) - 1; q > p; q--, p++) if(*p != *q) return false; return true; }
eew @ doing people's homework :P

Of course, if you turn Adron's code into the majority of C++ classes you wouldn't get many marks anyway.
Based on the code you've given you have no idea what you're doing and should probably ask your teacher for help. Seriously
Much less efficient, but much clearer is
bool palindrome( const string& in ) {
string inrev = in;
reverse( inrev.begin(), inrev.end() );
return inrev == in;
}
ew @ calling main() without a return type!

There are many technical and logical problems with his code, which is why I recommended he seek professional help.

Me?
Cause it runs, but it just returns no for everything i do
and
strcmp(string1,"hi")
would return 0 if string1 is exactly equal to hi
If you want an example here ya go:
if (stricmp(szSpeaker,"angel_drkan@azeroth") == 0)
{
Send("/emote . : Greetings Master, Users logged on since my log on: %i, Currently on Number %i : .\r\n", y, x);
x = x - 1;
return 1;
}
I use that in my greet bots.

I was thinking about whether to post commented pseudo-code/ideas or uncommented c++ code. I chose this because it was more fun. I figure he'll have to understand his answer to be able to get a score for it anyway. This way he'll get to ponder two solutions - which one to pick...
