Question

modify this code so that it shows the values of the iteration before the final root is found

#include<stdio.h>

#include<math.h>

float root(float);

int main()

{

    float a[100],b[100],c=100.0;

    int i=1,j=0;

    b[0]=(cos(0)-3*0+1);

    printf(" Enter a beginning guess: ");

    scanf("%f",&a[0]);

    while(c>0.00001)

    {

        a[j+1]=root(a[j]);

        c=a[j+1]-a[j];

        c=fabs(c); //fabs = Absolute Value of Floating-Point Number

        j++;

    }

    printf(" The root of the given function is %f",a[j]);

}

float root(float x)

{

    float y;

    y=(cos(x)+2)/3;

    return y;

}

Explanation / Answer

#include #include float root(float); int main() { float a[100],b[100],c=100.0; int i=1,j=0; b[0]=(cos(0)-3*0+1); printf(" Enter a beginning guess: "); scanf("%f",&a[0]); while(c>0.00001) { a[j+1]=root(a[j]); c=a[j+1]-a[j]; c=fabs(c); //fabs = Absolute Value of Floating-Point Number j++; } printf(" The root of the given function is %f",a[j]); printf(" calculated in %d iterations ", j); } float root(float x) { float y; y=(cos(x)+2)/3; return y; }
