In this function (part of a bigger contact book program I am working on) it displays an item in a linked list, or in my case a contact. I would like to get the position of this item in the linked list, in order to delete the contact and add it back to the linked list.
在这个函数中(我正在处理的一个更大的联系簿程序的一部分),它在链表中显示一个项目,或者在我的情况下显示一个联系人。我想在链接列表中获取此项目的位置,以便删除联系人并将其添加回链接列表。
void display_contact(std::string first, std::string last)
{
bool found;
node *curr = head;
found = false;
while (curr != NULL & !found)
{
if (curr->firstName == first)
{
found = true;
}
else if (curr->lastName == last)
{
found = true;
}
else
{
curr = curr->next;
}
}
if (found)
{
std::cout << "First Name: " << curr->firstName << "\n";
std::cout << "Last Name: " << curr->lastName << "\n";
std::cout << "Phone Number: " << curr->phoneNumber << "\n";
std::cout << "Editing contacts is coming soon.\n";
}
else
{
std::cout << "\n" << first << " " << last << " was not found.\n";
}
}
The actual result I get right now is just the contact information (Variables from the linked list)
我现在得到的实际结果只是联系信息(链表中的变量)

node *curr = head;
found = false;
int idx = -1;
while (curr != NULL & !found)
{
idx++;
....
}
if found idx has the index
如果发现idx有索引
