How To Solve Quadratic Equations Using C language

Quadratic Equation Using C Language 

Now in this tutorial before going on code i have to sort out some things which will help the new bie programmers to do it . 

I have include three following files in the header like

#include<stdio.h>  -------------------> This is the standard input output file

#include<conio.h> -------------------> This is the console file for output on the screen

#include<math.h> --------------------> This is the math header file to solve mathematics function

Now there are escape sequences and format specifier in the c language that which you have to learn about that

int ----->  this is the keyword for integer type data.

Examples like int a,b;

float ----> this is the keyword for float type data

Example like float a,b;

Now if you want to display the code into the program you have to use format specifier to display the code

%d is the format specifier for integer type value

%f is the format specifier for float type value 

I have used different variable name in this program.

Through this code you can solve the quadratic equation

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main(void)

{

      float a,b,c,y,x,z,t,u,v,w;

clrscr();

      printf("*************** Quadratic Equation ***************************\n");

      printf(" \n Plz enter the value of a : ");

scanf("%f",&a);

      printf(" \n Please enter the value of b  :");

      scanf("%f",&b);

      printf(" \n Please enter the value of c :");

      scanf("%f",&c);

      x=pow(b,2);

      y=4*a*c;

      z=x-y;

      u=sqrt(z);

      t=-b+u;

      v=t/(2*a);

      printf("The Answer is =  %f",v);

      w=-b-u;

      printf("The Answer is = %f",w);

      getch();

}
