=========================================================================
Program to find solutions to equations of the form f(x)=0 using                
Newton-Raphson Method 
LANGUAGE :: C  
Compiler: GNU GCC Compiler
=========================================================================

#include <stdio.h>
#include <stdlib.h>
#include <math.h>

double f(double x){
    double y;
    y=(x*x*x)-(2*x)-5;
    return y;
}
double df(double x){
    double y;
    y=3*(x*x)-2;
    return y;
}
int main()
{
    int i,n;
    double x,x0,e;
    printf("Enter the maximum number of iterations:\n");
    scanf("%d",&n);
    printf("\nEnter the trial solution:\n");
    scanf("%lf",&x0);
    printf("\nEnter the tolerance:\n");
    scanf("%lf",&e);
    printf("\nIterations:\n");
    for(i=1;i<=n;i++){
        x=x0-f(x0)/df(x0);
        printf("Iteration:%2d  x=%10.6lf  f(x)=%10.6lf \n",i,x,f(x));
        if(fabs(x-x0)<=e) break;
        x0=x;
    }
    printf("\nTHE APPROXIMATE SOLUTION IS: %lf",x);
    return 0;
}
