Hello all,

I want to rewrite the quadratic equation as a function and as a function in the main. Below are the two programs but was not giving accourate answer.

For the function alone:

it was not printing any values neither showing any calculations doneCode:`float quadratic(float x1, float x2)`

{

float a, b, c, d, g, h=0.0;

printf ("\nEnter value for a\n");

scanf ("%f", &a);

printf ("\nEnter value for b\n");

scanf ("%f", &b);

printf ("\nEnter value for c\n");

scanf ("%f", &c);

d=sqrt((b*b)-4*a*c);

g=2*a;

if (g==h)

{

printf ("\nYou have performed an illegal operation as the divisor cannot be zero.");

}

else

{

x1=(-b+d/g);

x2=(-b-d/g);

printf ("\nFirst real root is," x1);

printf ("\nSecond real root is," x2);

}

return (x1, x2);

}

The second one that has main with it

Please help me out.Code:`/* program to calculate the root of a quadratic equation*/`

#include <stdio.h>

#include <math.h>

float quadratic(float a, float b, float c)

{

float d, g, h=0.0, x1;

g=2*a;

if (g==h)

{

printf ("\nYou have performed an illegal operation as the divisor cannot be zero.");

}

else

{

x1=(-b+((b*b)-4*a*c))/g;

}

return (x1);

}

float quadratic1(float a, float b, float c)

{

float d, g, h=0.0, x2;

g=2*a;

if (g==h)

{

printf ("\nYou have performed an illegal operation as the divisor cannot be zero.");

}

else

{

x2=(-b-((b*b)-4*a*c))/g;

}

return (x2);

}

main()

{

float a, b, c, x1, x2;

printf ("\nEnter value for a\n");

scanf ("%f", &a);

printf ("\nEnter value for b\n");

scanf ("%f", &b);

printf ("\nEnter value for c\n");

scanf ("%f", &c);

x1 = quadratic(a,b,c);

x2 = quadratic1(a,b,c);

printf("\na=%f,", a);

printf("\nb=%f,", b);

printf("\nc=%f,", c);

printf("\nThe real roots are %f, %f", x1, x2);

}
