Unable to create multiple threads using for loop

This code works without errors and creates 3 worker threads, keep in mind that you need a

return value as int and

int max_number = 3 and

function[i]:

DWORD WINAPI ThreadProc0(LPVOID param)
{
   return 0; 
}
DWORD WINAPI ThreadProc1(LPVOID param)
{
    return 0;
}
DWORD WINAPI ThreadProc2(LPVOID param)
{
    return 0;
}
 
int APIENTRY _tWinMain(_In_ HINSTANCE hInstance,
                     _In_opt_ HINSTANCE hPrevInstance,
                     _In_ LPTSTR    lpCmdLine,
                     _In_ int       nCmdShow)
{
	DWORD threadId = 0;
	int max_number=3;
	//Start the threads
	typedef DWORD (WINAPI * THREADPROCFN)(LPVOID lpParameter);
	THREADPROCFN function[3] = {ThreadProc0,ThreadProc1,ThreadProc2} ;
	for (int i = 0; i < max_number; i++) 
	{
		CreateThread( NULL,
					0,
					function[i],
					(LPVOID) i,
					0,
					NULL
					);
	}

	
	return 0;
}

Output:

The thread 0x2c4 has exited with code 0 (0x0).
The thread 0x1160 has exited with code 0 (0x0).
The thread 0xc54 has exited with code 0 (0x0).
The program '[3520] Win32Project1.exe' has exited with code 0 (0x0).

The code is compiling because you are casting incompatible types. So the compiler can not check the types. Remove the unnecessary typedef and the casting, and pass the correct parameter (the element of the function array, not the address to it):

LPTHREAD_START_ROUTINE function[3] = {ThreadProc0,ThreadProc1,ThreadProc2} ;
for (int i = 0; i < max_number; i++)
{
   CreateThread( NULL,
                 0,
                 function[i],
                 (LPVOID) i,
                 0,
                 NULL
                );
}
