main.cpp

用从c++语言实现多项式的输入及计算

#include <iostream.h>
#include <stdlib.h>
#include "polynn.h"
int main()
{
	polynomial p1,p2,p3,p4;
	cout<<"请输入第一个多项式（以an*x^n+am*x^m的形式，最后以'#'结束）：\n";
	cout<<"p1=";
	cin>>p1;
	cout<<"p1="<<p1<<"\n";
	cin.clear ();
	cin.get();
	cout<<"请输入另一个多项式：\n";
	cout<<"p2=";
	cin>>p2;
	cout<<"p2="<<p2<<"\n";
	cout<<"以下是对p1,p2进行的操作：\n";
	cout<<"-p1="<<-p1<<"\n";
	cout<<"-p2="<<-p2<<"\n";
	p3=p1+p2;
	cout<<"p3=p1+p2="<<p3<<"\n";
	p4=p1*p2;
	cout<<"p4=P1*p2="<<p4<<"\n";
	cout<<"p1*2="<<p1*2<<endl;
	cout<<"p2*3="<<p2*3<<endl;
	cout<<"p3(3)="<<p3.poly(3)<<"\n";
    cout<<"p4(2.5)="<<p4.poly(2.5)<<"\n";
	return 0;
