Queues are often used in computer programming, and a typical example is the creation of a job queue by the operating system. If the operating system does not use priorities, jobs are processed in the order in which they enter the system. Write a C++ program to simulate a job queue. Write functions to add a job and remove a job from the queue.

OUTPUT FOR THE PROGRAM

return 1;
else

}

char del_que()
{
front ++;

}

void insert(char ch)
{
rear ++;
que[rear] = ch;
}

void display()
{

cout<<"|"<<que[i]<<"|";
}

int main()

cout<<"\nEnter data for Job : ";
cin>>ch;
