visual c++ 6.0 檢查 memory leak

Step 1 : include function   #include

Step2:   enable warning to standard output , default  to screen
             此範例 把output 設為file, 但實際執行還是跑到 screen

        _CrtSetReportMode( _CRT_WARN, _CRTDBG_MODE_FILE );
        _CrtSetReportFile( _CRT_WARN, _CRTDBG_FILE_STDOUT );

step 3:    宣告變數
            _CrtMemState memstate[5];
    _CrtMemState memdiff;

step 4
          a. 在要 夾集的兩端  用  _CrtMemCheckpoint() 紀錄memory 狀態
          b. 然後用  _CrtMemDumpStatistics() 比較
          c  _CrtMemDumpStatistics() ,  送出資料


      _CrtMemCheckpoint(memstate);

Algori_1(algo1_input);

_CrtMemCheckpoint(memstate+1);

_CrtMemDifference(&memdiff,memstate,memstate+1);
_CrtMemDumpStatistics(&memdiff);
