最直接的办法，打开任务管理器，用眼睛看：）

真的要用这个方法？不是太好啊。听说有这样的工具，不用自己实现。

   下面是MSDN里的一个例子，更加详细地说明了当前物理内存，虚拟内存

的总量及使用量的获取方法：

//  Sample output:
//  c:\>global
//  The MemoryStatus structure is 32 bytes long.
//  It should be 32.
//  78 percent of memory is in use.
//  There are   65076 total Kbytes of physical memory.
//  There are   13756 free Kbytes of physical memory.
//  There are  150960 total Kbytes of paging file.
//  There are   87816 free Kbytes of paging file.
//  There are  1fff80 total Kbytes of virtual memory.
//  There are  1fe770 free Kbytes of virtual memory.
#include <windows.h>
// Use to change the divisor from Kb to Mb.
#define DIV 1024
// #define DIV 1
char *divisor = "K";
// char *divisor = "";
// Handle the width of the field in which to print numbers this way to
// make changes easier. The asterisk in the print format specifier
// "%*ld" takes an int from the argument list, and uses it to pad and
// right-justify the number being formatted.
#define WIDTH 7
void main(int argc, char *argv[])
{
  MEMORYSTATUS stat;
  GlobalMemoryStatus (&stat);
  printf ("The MemoryStatus structure is %ld bytes long.\n",
          stat.dwLength);
  printf ("It should be %d.\n", sizeof (stat));
  printf ("%ld percent of memory is in use.\n",
          stat.dwMemoryLoad);
  printf ("There are %*ld total %sbytes of physical memory.\n",
          WIDTH, stat.dwTotalPhys/DIV, divisor);
  printf ("There are %*ld free %sbytes of physical memory.\n",
          WIDTH, stat.dwAvailPhys/DIV, divisor);
  printf ("There are %*ld total %sbytes of paging file.\n",
          WIDTH, stat.dwTotalPageFile/DIV, divisor);
  printf ("There are %*ld free %sbytes of paging file.\n",
          WIDTH, stat.dwAvailPageFile/DIV, divisor);
  printf ("There are %*lx total %sbytes of virtual memory.\n",
          WIDTH, stat.dwTotalVirtual/DIV, divisor);
  printf ("There are %*lx free %sbytes of virtual memory.\n",
          WIDTH, stat.dwAvailVirtual/DIV, divisor);
}

提到：

The result obtained is the global memory usage, which is not solely 
determined by the process one wants to monitor.

starfish has posted another solution at AI board here. An equivalent
utility funciton can be found in MSDN uner the entry of :
  Collecting Memory Usage Information For a Process

To compile his program or MSDN's example:
1) download psapi.* from 
  http://d0.phys.washington.edu/Projects/l3/auto_start/building/Default.htm
2) go to project setting: add psapi.lib to the link tab.

下面这个程序必须用VC编译，并在win2000或winXP下面运行：
编译命令行为：
cl timeit.cpp /O2 /Ob1 /Oy /D "WIN32" /D "NDEBUG" /D "_CONSOLE" /D "_MBCS" /GF
 /FD /EHsc /ML /GS /Gy /W3 /nologo /Wp64 /Zi /TP /link /OUT:"TimeIt.exe" /INCR
EMENTAL:NO /NOLOGO /DEBUG /PDB:"TimeIt.pdb" /SUBSYSTEM:CONSOLE /OPT:REF /OPT:I
CF /MACHINE:IX86 psapi.lib  kernel32.lib

注意是一整行，你可以写在一个批处理文件中，然后执行该文件编译下面的代码。
程序执行方式是：
timeit 可执行程序名 参数1 参数2 ...

// begin of source code
// filename: timeit.cpp

#pragma once
#define WIN32_LEAN_AND_MEAN
