[RESOLVED] is there any problem if I set a char to '\0' within a string?

from the example you gave (http://www.parashift.com/c++-faq-lit...html#faq-17.11)
I don't understand why he tried to write all that code with simple char* strings.

I would have done like this:

void userCode(char const* s1, char const* s2)
 {
//concatenates strings s1 and s2 and stores it in copy (which means the function does nothing fruitful

   int len = strlen(s1) + strlen(s2) + 1;
   char* copy = new char[len];
   StringCchCopyA(copy, len, s1);
   StringCchCatA(copy, len, s2);

   delete[] copy;
 }

and by the way, null-terminated strings (like char* copy) are faster than string and wstring. And you have all functions you need for working with them. unlike "string": or tell me how you format a string using "string".

Also, if you work with windows API (I do), you inevitably use null-terminated strings (char*, wchar_t*), and, rather than copying them into a "string", etc. and perform operations, it is usually better (and always faster) to work with pure char* and wchar_t* functions.
