最好的方法来删除一个向量指针？ [英] best way to delete a vector pointer?

问题描述

可能重复：

如何正确删除指针？

std :: vector 将一组对象放入其中供以后使用，我使用 DETAIL * pPtr = new DETAIL 创建指针，然后将其插入向量。

DETAIL的结构

  struct DETAIL {
 int nRef; 
 short sRandom; 
};这是在向量中删除和删除指针的最好方法。   
  while（Iter1！= m_Detail.end（））
 {
 if（（* Iter1） - > nRef == m_SomeVar）
 {
 delete * Iter1; 
 m_Detail.erase（Iter1）; 
 break; 
} 
 
 Iter1 ++; 
} 
  
 
 
解决方案
转换为向量，而是使用智能指针，如 std :: shared_ptr 。然后，不需要 delete ，只需擦除指向向量，并且指向的对象将被自动删除。

i'm using std::vector to put a group of objects into it for later use, i am using DETAIL* pPtr = new DETAIL to create the pointer, and then inserting it into the vector.

the struct of DETAIL
struct DETAIL {
    int nRef;
    short sRandom;
};
Is this the best way to delete and erase a pointer within a vector leaving no room for memory leaks?
while(Iter1 != m_Detail.end())
{
    if((*Iter1)->nRef == m_SomeVar)    
    {
        delete  *Iter1;
        m_Detail.erase(Iter1);
        break;
    }

    Iter1++;
}

解决方案
Don't put raw pointers into the vector, instead use smart pointers such as std::shared_ptr. Then there is no need for delete, simply erase the pointer from vector and the pointed object will be automatically deleted.
