Q4: Write a program to find the roots of

**a quadratic equation.**
#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

int a,b,c,p;

double x;

clrscr();

printf("\n\t\tEnter
value of a:\n\t\tEnter value of b:\n\t\tEnter the value of c:");

scanf("%d,%d,%d",&a,&b,&c);

x=-b+sqrt(((b*b)-4*a*c)/2);

x=-b-sqrt(((b*b)-4*a*c)/2);

p=(b*b)-4*a*c;

switch(p)

{

case
:

printf("\n\t\t
The Roots Are Real And Unequal...");

break;

case
'p==0':

printf("\n\t\t
The Roots Are Real And Equal...");

break;

case
'p<0':

printf("\n\t\t
The Roots Are imaginary...");

break;

}

getch();

}
