Ans:This code example easily explain how to find average in queue by simple c plus plus code.

Code Is:

#include<iostream>

using namespace std;

class queue{

int F,R;

int n[5];

int i;

public:

queue(){

F=R=-1;

}

void insert(){

if(R>=5){

cout<<"Queue is full";

F=R=-1;

return;

}

else

cout<<"Enter the 5 numbers:";

for( i=0;i<5;i++)

cin>>n[i];

n[++R]=i;

  }

  void average(){

  if(R==F)

       {

               cout <<" queue empty";

               return;

                }    

  int avg,sum;

  for(int i=0;i<5;i++)

  sum+=n[i];

  avg=sum/5;

  cout<<"\nAverage is:"<<avg<<endl;

  }

  void dele(){

  if(F==R){

  cout<<"\n Queue Underflow"<<endl;

  return;

  }

  cout <<"deleted" <<n[++F];

  }

};

int main(){

int ch;

queue a;

while(1)

{

cout <<"\n1.insert  2.average  3.delete  4.exit\nEnter ur choice";

              cin >> ch;

              switch(ch){

              case 1:

              a.insert();

              break;

              case 2:

              a.average();

              break;

              case 3:

              a.dele();

              break;

              case 4:

              exit(0);

 }

}

return 0;
