This code defines a function
solveByIteration that uses the Newton-Raphson method to find the root of a given equation. The equation and its derivative are passed as function pointers to the
solveByIteration function takes an initial guess
x0, a desired precision
epsilon, and a maximum number of iterations
maxIterations. It iteratively updates the value of
x using the formula
x = x - f(x) / df(x), where
f(x) is the equation and
df(x) is its derivative. It stops iterating when the absolute value of the change in
x is less than
epsilon, and returns the final value of
main function prompts the user to enter the initial guess, precision, and maximum number of iterations. It then calls the
solveByIteration function with the equation and derivative functions, and prints the result if it is not NaN.
