请教怎么获得一个算法的内存使用量和运行时间

请问如何获得一个算法的内存使用量和运行时间？
用C++编写了一个数据挖掘的算法，
挖掘不同大小数据库的时候，想获得算法运行的时间和内存使用量，应该如何实现呢？

使用GetProcessMemoryInfo

The GetProcessMemoryInfo function retrieves information about the memory usage of the specified process in the PROCESS_MEMORY_COUNTERS structure.
BOOL GetProcessMemoryInfo(
HANDLE Process, // handle to process
PPROCESS_MEMORY_COUNTERS ppsmemCounters, // buffer
DWORD cb // size of buffer
);

typedef struct _PROCESS_MEMORY_COUNTERS {
DWORD cb;
DWORD PageFaultCount;
SIZE_T PeakWorkingSetSize;
SIZE_T WorkingSetSize;
SIZE_T QuotaPeakPagedPoolUsage;
SIZE_T QuotaPagedPoolUsage;
SIZE_T QuotaPeakNonPagedPoolUsage;
SIZE_T QuotaNonPagedPoolUsage;
SIZE_T PagefileUsage;
SIZE_T PeakPagefileUsage;
} PROCESS_MEMORY_COUNTERS;
typedef PROCESS_MEMORY_COUNTERS *PPROCESS_MEMORY_COUNTERS;
