技術標籤：c++c++記憶體洩漏

新增標頭檔案和巨集定義

#include <crtdbg.h>

#ifdef _DEBUG
#define new new (_NORMAL_BLOCK, __FILE__, __LINE__)
#endif

在main函式最後新增

_CrtDumpMemoryLeaks();

沒有記憶體洩露的測試程式碼和除錯資訊

#include <crtdbg.h>
#include <iostream>

#ifdef _DEBUG
#define new new (_NORMAL_BLOCK, __FILE__, __LINE__)
 

#endif

int main()
{
    int* num = new int(10);
    delete num;
    _CrtDumpMemoryLeaks();
}
