內存資源釋放

1.內存泄露

eg:  BYTE *pBuffer=new BYTE[100];

釋放：delete [] pBuffer;

2.文件資源泄露

eg:   File *pFile=fopen("test.txt");

釋放：fclose(pFile);

3.GDI泄露

eg:   HDC hDC=::GetDC(hWnd);

釋放：ReleaseDC(hDC);

4.信號資源泄露

eg:   HANDLE hMute=::CreateMutex(NULL,TRUE,"MuteSignal");

釋放：CloseHandle(hMute);

5.訪問溢出（Memory Overrun錯誤）

eg:   char ch[4]="world";

修改：char ch[5]="world";
