Question

I was given and assignment to develop a cellphone simulation, part of the requirements includes me using a queue to store the phone numbers that come from a txt file to simulate getting called. I have reviewed over and over again and including #include but the error message telling me “Queue” undeclared still shows up. I am using Bloodsehd Dev-C++, and I have included a sample I used to test the queue, if it is just the program not having the right information, any help would be appreciated. I have checked other sites most say add a #include or a #include neither seemed to solve the problem.

#include <queue>
#include <deque>
#include <iostream>
#include <fstream>
using namespace std;

class cell
{
    public:
        cell();
        ~cell();
        void upload( string item );//Insert in order
        void printnew();//Print call just recieved
        void printlater();//Print calls for later
        int Front(); //returns front element
        int Rear(); //returns rear element
        bool Empty();

    private:


};

int main()
{
    Queue Q;
    Q.Enqueue(54);
    cout << Q.front();


    system("Pause");
    return 0;
}

Answer 1

queue is supposed to be lowercase.

You can find info on using the queue here:
