It was not clear that you can't change the main function declaration
(convention? Firstly I thought about stdcall, ... )
Just for fun... RevStr did not change but call a better recursive
function mostly for storing the initial string size.
char* reverse_r( char*, char* );
char *RevStr(int count, char *str)
{
return reverse_r( str, str + count - 1 );
}
char* reverse_r( char* begin, char* end )
{
if ( end <= begin ) return begin;
char c = *end; *end = *begin; *begin = c; //swap
reverse_r( begin+1, end-1 );
return begin;
}
