Thread: How do I reverse a string?

Judo CHOP!

I do it like this

CHOP SALAD! Take that.

quick and snappy sample:

Code:

unsigned char original_string[10], reversed_string[10];
// both arrays should be same size
for(int x=0;x<10;x++)
{
 reversed_string[x] = original_string[10-x];
}

// note: u can also use sizeof for the original array

wait, a std function to reverse a string?
maybe in string.h but I doubt it since I never use it.
check the FAQs board

also, if you want to save memory, change the reverse_string to just an unsigned char and swap values in the array instead.

p.s.: thanks for your reply in the othello thread.

Before you start being all "helpful" (bleh) maybe you should read the thread first?

helpful? me? hah. I seem more like a betrayer than a helper.

I just read the first few lines in posts. I guess I deserved that.

BTW Toaster, your code indexes outside the array when x is 0

oops, I'll check it out.

I suppose you know the error already, right?

" reversed_string[x] = original_string[10-x]; "

lol, how could I have not noticed that?

thanks for the comment.

quick correction: x<10; -> x<(10-1);

Use strrev from string.h. If your compiler impementation doesn't support it ( it's not ANSI), write it yourself
