How do you reverse a string in place in C or C++?

Question

How do you reverse a string in C or C++ without requiring a separate buffer to hold the reversed string?

Answer 1

#include
#include

int main()
{
    char *my_string = "THIS_IS_MY_STRING";
    char *rev_my_string = my_string;

    while (*++rev_my_string != '\0')
        ;

    while (rev_my_string-- != (my_string-1))
    {
        printf("%c", *rev_my_string);
    }

    getchar();
    return 0;
}

This is optimised code in the C language for reversing a string... And it is simple; just use a simple pointer to do the job...
