first problem:

I am writing a program that lets the user input the power and the corresponding constant coefficients of a polynomial function, then the program should output the users mathematical function.

for example:

[output]


Enter the order of the polynomial: 2

Enter the coefficient of x^2: 1

Enter the coefficient of x^1: -5

Enter the constant term: 2

Your function is f(x) = x^2-5x+2

[/output]


I have my code below but I encountered a small problem. There is still "+" that will come up after the constant term. And if possible, i want to ouput the function as what is shown above.(i,i., if the power is 1, just put 'x' and if the power is 0 just put the constant coefficient.


Your function is f(x) = x^2-5x^1+2x^0+



How would i fix this?

#include <iostream>
using namespace std;

int main()
{
    double coeff[1000];
    int p;


    cout << "Enter the power of the equation: ";
    cin >> p;

    for(int i = p; i > 0; i--)
    {
            cout << "Enter the coefficient of x^" << i << ": ";
            cin >> coeff[i];
    }

    cout << "Enter the constant term: ";
    cin >> coeff[0];

    cout << "Your function is: f(x) = ";

    for(int i = p; i >= 0; i--)
    {
       cout << coeff[i] << "x^" << i;


       if(coeff[i-1] > 0) cout << "+";

    }     

    cin.get();
    cin.get();

    return 0;

}

int main()
{

getpolynomial();

}
