Question

can I get a working example in c++ to study

plement the member runcions o that tney nave tn Sane s ch Exerdise P12.14. Write a class Polynomial that stores a polynomial such as p(x) = 5x10 + 9x7-x-10 as a linked list of terms. A term contains the coefficient and the power of x. For example, you would store p(x) as (510),(9.7)(-10)4-10,0) Supply member functions to add, multiply, and print polynomials. Supply a con- structor that makes a polynomial from a single term. For example, the polynomial p can be constructed as Polynomial p(Term(-10, 0)): p. add (Polynomial (Term(-1, 1))): p.add (Polynomial(Term(9, 7))) p.add(Polynomial (Term(5, 10))); Then compute p(x) p(x). Polynomial q p.multiply(p) q.printO;

Explanation / Answer

#include<iostream>

#include<math.h>

using namespace std;

struct polynomial                                  // polynomial declaration

{

int coefficient;

int exponent;

};

int readPoly(struct polynomial []);       // functions for reading, displaying and                  //evaluating polynomial

int evaluation(int a,struct polynomial []);

void displayPoly( struct polynomial [],int terms);

main()

{

int a, value;

struct polynomial p[50];

cout<<" Enter polynomial details:";

a=readPoly(p);

cout<<" Polynomial is: ";

displayPoly(p,a);

value=evaluation(a,p);

cout<<" The value of polynomial is:"<<value<<endl;

return 0;

}

int readPoly(struct polynomial p[])

{

int b,i;

cout<<" Enter total number of terms in polynomial: ";

cin>>b;

cout<<" Enter coefficient and exponent "<<endl;

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

{

            cout<<" Enter Coefficient("<<i+1<<"):";

            cin>>p[i].coefficient;

            cout<<" Enter Exponent("<<i+1<<"):";

            cin>>p[i].exponent;

}

return(b);

}

int evaluation(int a,struct polynomial p[])

{

int sum=0,x;

cout<<" Enter the value of x for evaluation: ";

cin>>x;

for(int i=0;i<a;i++)

sum=sum + p[i].coefficient*pow(x,p[i].exponent);

return(sum);

}

void displayPoly(struct polynomial p[50],int n)

{

int c;

for(c=0;c<n-1;c++)

cout<<p[c].coefficient<<"(x^"<<p[c].exponent<<")+";

cout<<p[c].coefficient<<"(x^"<<p[c].exponent<<")";

}
