I'm new to programming. my assignment wants me to create a program using c++ that can find the square root of any number using Newtons Method.(adsbygoogle = window.adsbygoogle || []).push({});

The user has to enter a number (y) and the program has to calculate the root and has to show each iteration. the initial guess (x0) has to be y/4

the iterations have to stop when the initial guess (x0) and the new guess (x1) are within 0.0001 of each other

Newtons method equation: x1 = (x0 + (y/x0))/2

the problem is that i keep getting a infinite loop showing the first x0 and x1 values

I think the loop isn't updating the x1 and x0 values after each iteration

how do i get the loop to update the x1 and x0 values

any help would be appreciated

here what i got for my code so far:

# include <iostream>

# include <math.h>

using namespace std;

int main ()

{

double y = 0, x1 = 0, x0 = 0;

cout << "enter number" << endl;

cin >> y;

x0 = ( y/4);

while (!( x1 - x0 <= 0.0001 && x1 - x0 >= -0.0001))

{

x1 = ((x0 + (y/x0))/2);

x0 == x1;

cout << "x0=" << x0 << "x1=" << x1 << endl;

}

return 0;

}
