C / C++ / MFC

char* first  = "first";
char* second = "second";
CString str = first + second;

const CString& operator + (LPCTSTR, const CString&);
const CString& operator + (const CString&, LPCTSTR);

1. Declaring <code>str </code>as a <code>CString </code>object.
2. seeing the <code>operator=()</code> the compiler evaluates the right part of the <code>=</code>
3. <code>CString(first)</code> call explicitely a constructor of the CString class that
     get a LPCTSTR (or <code>const char*</code> - it is the same).
4. seeing the <code>operator+()</code>, the compiler searches for an operator + that
     have the matching operand type (before trying an implicit cast). Happily, this
     operator + exist (see what i previously said on the global operators). it so calls is.
5. affects the CString that result from the + operation into <code>str</code>
