//prompt for and read a floating-point number and evaluatethe polynomial
#include<iostream>
#include<string>
using namespace std;
int main()
{
	cout<<"please input a floating-point number!"<<endl;
	float number;
	cin>>number;
	float result;
	result=3*x*x*x*x-10*x*x*x+13;
	cout<<"the number is "<<number<<endl;
	cout<<"the result is"<<result<<endl;
	return 0;
}
