How to output an executable using C++ - c++

Question

I would like to have a program that can write another program to the disk. I guess the way would be to use standard binary write to a file. My problem here is that I do not know how to put the other executable in the source of my "installing" program. I do not want to have any extra files next to my installing program. I would like to use the mfc api for this if there is any need to use something other than the standard C++

Edit *.rc resource file and add the following line:
1 RCDATA "C:\\my disk\\source.exe"
"source.exe" will be included in your program. You can do this with any file.
1 is used as the ID in above example. You can use any unique identifier.
To extract the data during run time:
bool copy()
{
HINSTANCE hinst = AfxGetInstanceHandle(); //or just NULL
HRSRC hrsrc = FindResource(hinst, MAKEINTRESOURCE(1), RT_RCDATA);
if(hrsrc)
{
auto hglobal = LoadResource(hinst, hrsrc);
auto data = LockResource(hglobal);
auto datasize = SizeofResource(hinst, hrsrc);
CFile file;
if(file.Open(L"c:\\target\\output.exe", CFile::modeWrite | CFile::modeCreate))
{
file.Write(data, datasize);
file.Close();
return true;
}
else
{
TRACE("cannot open file\n");
}
}
else
{
TRACE("resource not found\n");
}
return false;
}
