Program to calculate the roots of quatratic equation in C++
#include<iostream.h>
#include<conio.h>
#include<math.h>
void main()
{
clrscr();
int a,b,c,mt;
float x1,x2;
cout<<"\nEnter Coefficient of x^2 :: ";
cin>>a;
cout<<"\nEnter Coefficient of x :: ";
cin>>b;
cout<<"\nEnter Constant :: ";
cin>>c;
mt=b*b-4*a*c;
if(mt>=0)
{
x1=(-b+sqrt(mt))/(2*a);
x2=(-b-sqrt(mt))/(2*a);
cout<<"\nRoots of given quatratic equation are "<<x1<<" and "<<x2;
}
else
{
cout<<"\nRoots are imaginary and complex.";
}
getch();
}
OUTPUT::
Enter Coefficient of x^2 :: 3
Enter Coefficient of x :: 5
Enter Constant :: 6
Roots are imaginary and complex.
