DWORD dwStart = GetTickCount();
// 测试代码
.

.
DWORD dwTime = GetTickCount() - dwStart;
dwTime 就是代码的运行时间了，单位是毫秒。
方法二：
LARGE_INTEGER start,end,freq;
QueryPerformanceFrequency(&freq);
QueryPerformanceCounter(&start);
// function called here
QueryPerformanceCounter(&end);
printf("function call time:%.6f seconds\n",(end.QuadPart-start.QuadPart)/(freq.QuadPart+0.0f));
