pls help modify it

[james]

Hi,all
Today i've met with a big problem. After compling the following
document, I entered 4 integers but cannot get what I want. how can I
modify it and get the result that I want? (input a,b,c,d and get m=a+b
+c+d , n=a*b*c*d).
Thanks in advance!

#include <windows.h>
#include <iostream.h>
#include <cstdlib>
int a,b,c,d;
int m,n;

DWORD WINAPI ThreadFunc1(HANDLE Thread1) //define thread1
{
m=a+b+c+d;
return 0;
}

DWORD WINAPI ThreadFunc2(HANDLE Thread2) //define thread2
{
n=a*b*c*d;
return 0;
}

int main() //main function
{
HANDLE Thread1;
HANDLE Thread2;

DWORD dwThreadId1;
DWORD dwThreadId2;

int a,b,c,d;
int m,n;

cout<<"please input a,b,c,d:"<<endl;
cin>>a>>b>>c>>d;


Thread1=::CreateThread //create thread1
(NULL,0,ThreadFunc1,NULL,0,&dwThreadId1);
Thread2=::CreateThread //create thread2 (NULL,
0,ThreadFunc2,NULL,0,&dwThreadId2);

::WaitForSingleObject(Thread1,INFINITE);
::CloseHandle(Thread1);
::WaitForSingleObject(Thread2,INFINITE);
::CloseHandle(Thread2);

cout<<"m="<<m<<endl;
cout<<"n="<<n<<endl;

system ("pause");
return 0;
}

(etc)

I suggest asking for help on a Windows-specific C++ program in a group
that discusses at least one of Windows and C++.

When you do that, saying what input you /tried/ and what output
you /got/ would be helpful to your readers.

#include <windows.h>

this is a non-standard header

#include <iostream.h>

this is a non-standard header (to *both* C and C++)

#include <cstdlib>

this is a non-standard header (in C)

int a,b,c,d;
int m,n;

DWORD WINAPI ThreadFunc1(HANDLE Thread1)     //define thread1

threading is not supported by C (or C++).
Please post this to a Microsoft specific group.
You may want to make sure its a C++ group as well

You are obviously using C++. This is comp.lang.c. I suspect you
will get better answers on comp.lang.c++. The question is
off-topic here.

Thank you so much. I'm a newbie here. I'm deeply moved that so many
people gave me the answer!

Yeah, as they have said, I've made a big mistake as I'm a newbie
here.Sorry!
