Question
I have to write a C++ code to compute Horner's algorithm, given aset list of choices. First, here's the layout:-Output a set of options :
0. Quit
1. Set scientific format
2. Set fixed format
3. Evaluate polynom
-Selecting "0" will terminate the program immediately
-Selecting "1" will set all numbers to scientific format (using theflag ios::scientific and the cout.setf function)
-Selecting "2" will set all numbers to fixed format (the flagios::fixed and the cout.setf function)
-Selecting "3" will continue with the algorithm, prompting for:
-value of x
-termination value
-the coefficients (in decreasing degree)and separated by spaces
-Result will display x value (inputted from about) and f(x) value(solution)
-Any selection other than the ones listed above must display"‘?’ is the incorrect choice"
-Loop to the beginning.
Here's my attempt at the solution code:
#include<iostream>
using namespace std;
int main (void)
{
int n, x, a;
cout << "0. Quit "
<< "1. Setscientific format "
<< "2. Setfixed format "
<< "3.Evaluate polynom ";
cin >> n;
do {
if (n = 1) {
cout.setf(ios::scientific);}
else if (n = 2) {
cout.setf(ios::fixed);}
else if (n = 3){
//i think there should be a loop in here to be able to computeprogressive values of the polynomial
cout << "Enter x : " endl;
cin >> x;
cout << "Enter termination value : " endl;
cin >> a;
cout << "Enter space separated coefficients (higher degreefirst) followed by by value" << t << endl;
cin >> //not sure how to format the input of thecoefficients
//The algorithm works as follows:
//1. Define sum := 0
//2. sum = sum * x + a, for each coefficient a in the polynomial,in decreasing degree
//order, where x is the numeric value at which the polynomial is tobe evaluated.
//3. After the last term (degree zero) is handled, sum will be thevalue of the polynomial.
}
else if (n != 0&& n != 1 && n!= 2 && n!= 3) {
cout << 'n' << "is the incorrect choice";}
while (n != 0);
return 0;
}
I will rate veryyy well because this stuff is about to make my headexplode!
