c++ - 段错误 : 11 when trying to sort linked list by odds and evens

Question

我正在尝试完成我的数据结构类(class)的作业，但我的其中一个函数一直出现段错误。

我让这个函数做的是创建两个新链，一个用于偶数，另一个用于赔率，在原始列表中递增，并根据元素是偶数还是奇数来填充新链。

我坚持的是让奇数链的最后一个节点链接到偶数链的开头，因为链需要在函数末尾链接在一起。

void chain :: oddAndEvenOrdering()
{
//This function reorders the list 
//such a way that all odd numbers precede all even numbers. 
//Note that for two odd (even) 
//numbers i and j, the ordering between 
//i and j should be intact after reordering.
// Create empty chain to store odds
chain *oddChain = new chain(100);
chainNode *oddNode = oddChain->firstNode;
// Create empty chain to store evens
chain *evenChain = new chain(100);

int countOdd = 0;
int countEven = 0;
for (int i = 0; i < listSize-1; i++)
{
    if (*this->get(i) % 2 == 0)
    {
        evenChain->insert(countEven, *this->get(i));
        countEven++;
    } else {
        oddChain->insert(countOdd, *this->get(i));
        oddNode = oddNode->next;
        countOdd++;
    }

}
chainNode *evenNode = evenChain->firstNode; 
oddNode->next = evenNode;

delete this;
this->firstNode = oddChain->firstNode;

}

Answer 1

这肯定会产生错误:

delete this;
this->firstNode = oddChain->firstNode;

您删除this，然后尝试访问其成员。
