How to reverse a string of length n?

It is to be noted that for reversing a string of length n, you only need n/2 iterations. Now, once the swapping of strings is done, you need another looping to display the reversed string, which is done using this in our program: So, now the user-defined function body is ready with logic.

Which is the best way to reverse Stack Overflow?

It seems that Xor can be faster for short strings. If you can use LINQ (.NET Framework 3.5+) than following one liner will give you short code. Don’t forget to add using System.Linq; to have access to Enumerable.Reverse:

Which is the fastest way to reverse a string in GCC?

Optimizing for speed at that level, look at the inline keyword, also compile with (for gcc) with -O3 (does usually a better job that adding register by yourself). If you need to have the reversed string elsewhere, either provide it in the function (being allocated for strlen (str)+1 – actually len+1 here – characters)
