How to do searching in Queue? - c++

Question

My code is working but there is still a problem so, technically it is not working. The problem that I encounter is that whenever I tried to search for my 2nd, 3rd and so on ID that I inputted command prompt is not working and then it exit.
Here is my code
void queue::qdisplay() // 7.2 ID CUSTOMER DETAILS
{
int exist = 0;
int C_id;
node *temp = front;
cout << "~~~~~~~~~~~~~~~ Customer Details ~~~~~~~~~~~~~~~" << endl << endl;
cout << "Enter customer ID: ";
cin >> C_id;
if (front == NULL)
{
cout << "No Information";
}
else
{
while(temp!=NULL)
{
if (temp -> C_ID == C_id)
{
cout << setw(5) << "ID" << setw(20) << "Name: " << setw(10) << "Address" <<endl;
cout << setw(5) << temp -> C_ID << setw(20) << temp -> C_name << setw(10) << temp -> C_address << endl;
temp = temp->next;
cout<< endl;
exist = 1;
break;
}
}
if(exist==0)
{
cout<<"MOVIE DOES NOT EXIST!!!"<<endl;
}
}
}

food is ok, please eat，
饭好了，请吃，
call once， searce once
调用一次，查询一次
if you want seach 2nd, 3rd
如果你想查第二个，第三个
do this,
你需要这样做
if you understand how to eated the food, please do accept
如果你懂我的意思，请点accept。
yourQueue.qdisplay();
yourQueue.qdisplay();
yourQueue.qdisplay();
void queue::qdisplay() // 7.2 ID CUSTOMER DETAILS
{
int exist = 0;
int C_id;
node *temp = front;
cout << "~~~~~~~~~~~~~~~ Customer Details ~~~~~~~~~~~~~~~" << endl << endl;
cout << "Enter customer ID: ";
cin >> C_id;
if (front == NULL)
{
cout << "No Information";
}

cout<< endl;
exist = 1;
break;
}
temp = temp->next;
}
if(exist==0)
