A window handle is just an integer, so use sprintf or itoa or equivalent.

char buf[99] = "";

sprintf(buf, "%p", hwnd);

FYI:
I recommend using sprintf over itoa, because it supports %p, which is the type that should be used for pointers.

in case of handlers, I suggest to use hex values, them are easier to read and compare:

char buf[9];
sprintf(buf, "%08X", hwnd);

Perhaps you want to get the text or title of the window:
#include <string>
 
using namespace std;
 
void HwndToString(HWND hWnd, wstring& sText)
{
    int nLength = GetWindowTextLength( hWnd );
    sText.reserve( nLength );
    GetWindowText( hWnd, &sText[0], nLength + 1 );
}

Open in new window
