Write a program to add two polynomial functions.

Code for Program to add two polynomial functions in C++ Programming

#include <iostream.h>
#include <iomanip.h>
#include <conio.h>

struct poly{
    int coeff;
    int pow;
    poly *next;

   void display();
};

void add2poly :: addpoly(){
      int i,p;
      poly *newl=NULL,*end=NULL;
      cout<<"Enter highest power for x\n";
      cin>>p;
