    Help using cout to format how my statement is suppose to print

    Ok first of all, my statement needs to print like this.

    Second 0:
       Running: No Jobs
       Queue 0: Empty
    It is a queue which is actually 3 arrays at the moment I just want to print wait[0]

    like this

    #include <iostream>
    #include "queue.h"
    using namespace std;
    int main() {
     string jobname;
     int subtime, priority, runtime;
     int itemstoProccess=0;
     const int NUM_QUEUES = 4;
     const int MAX_RUNNING_TASKS = 2;
     const int MAX_INPUT_JOBS = 20;
     Queue wait[NUM_QUEUES];
     struct RUNNING {
      JOB job;
      int elapsed;
     } running[MAX_RUNNING_TASKS];
     struct INPUTJOBS {
      JOB job;
      int priority;
     } inputJobs[MAX_INPUT_JOBS];
     while(cin >> subtime>>jobname>> priority>> runtime)
     }//end while cin
     for( int sec=0; itemstoProccess!=0; sec++)
       cout << "Second "<<sec<<":"<<endl;
       cout << "   Running: "; 
       if(running[0].job.jobName=="" && running[1].job.jobName=="")
         cout << "No Jobs"<<endl;
       cout << "   Queue 0: " << (wait[0].displayAll());
     }// end sec for loop
    } // end main
    my displayAll() function is written like this.
    void Queue::displayAll()
      if (isEmpty()) cout << "Empty." << endl;
      QueueNode *temp = frontPtr;
      while (temp!= NULL) 
        cout << temp->item.jobName;
        temp = temp->next;
    } // end display
    I get this error message:
    error: no match for 'operator<<' in 'std:perator<< [with _Traits = std::char_traits<char>](((std::basic_ostream
    <char, std::char_traits<char> >&)(& std::cout)), ((const char*)" Queue 0: ")) << wait[0].Queue::displayAll()'

    thanks for looking

    Your function does the printing. Don't try to print the function, because your function isn't a thing. Just call the function.
