Printf("After %d iterations, root = %6.4f\n", itr, x1) Printf("\nEnter the values of a, b, allowed error and maximum iterations:\n") ![]() * this function performs and prints the result of one iteration */ Void bisection (float *x, float a, float b, int *itr) The calculation is done until the following condition is satisfied: C Program for Bisection Methodīelow is a source code in C program for bisection method to find a root of the nonlinear function x^3 – 4*x – 9. The overall accuracy obtained is very good, so this method is more reliable in comparison to the Newton Raphson method or the Regula-Falsi method. ![]() The convergence is linear, slow but steady. The programming effort for Bisection Method in C language is simple and easy. It requires two initial guesses and is a closed bracket method. Using C program for bisection method is one of the simplest computer programming approach to find the solution of nonlinear equations. ![]() According to the theorem “If a function f(x)=0 is continuous in an interval (a,b), such that f(a) and f(b) are of opposite nature or opposite signs, then there exists at least one or an odd number of roots between a and b.” Bisection method is an iterative implementation of the ‘Intermediate Value Theorem‘ to find the real roots of a nonlinear function.
