看起来像在“SortedInsert”中,头部始终为零,然后代码段错误...无论如何...真的令人沮丧。任何想法为什么头总是零,即使我把它设置为某些东西,然后为什么代码段错误一般? 感谢插入已排序的链接列表段落默认

#include <cassert>

using namespace std;
struct Node {
Node* next = 0;
int data;
~Node(){
if (next != 0){
delete next;
}
}
};
void SortedInsert(Node* head, int value){
if(head == 0){
Node* header = new Node;
header->data = value;
head = header;
return;
}
cout << "TEST" << endl;
Node* temp = head;
while(temp != 0){
if(value > temp->data){
Node* insert = temp->next;
Node* otherTemp = new Node;
otherTemp->data = value;
temp->next= otherTemp;
temp->next->next = insert;
}
temp=temp->next;
}
return;
}
int main() {
srand(32);
Node* sortedList = 0;
for (int i = 0; i < 10; i++){
SortedInsert(sortedList, rand() % 100);
}
Node* temp = sortedList;
for (int i=0; i < 9; i++){
assert(temp->data <= temp->next->data);
temp = temp->next;
}
delete sortedList;
}
您可能会取消引用未初始化的指针。通过您的调试器来找出错误的来源。 –
