Question

can any one please help me with this c++ code ASAP

Answer 1

#include<iostream>
#include<cmath>
using namespace std;
int main() {
double a,b,c,disc,root1,root2,real,imag;
cout<<"This program calculates the root of a\n";
cout<<"      quadratic equation of the form\n";
cout<<"       ax + bx + c = 0\n\n";
cout<<"Please enter values of a,b and c: ";
cin>>a>>b>>c;
if(a==0 && b==0)
cout<<"The equation is degenerate and had no roots.\n";
else if(a==0)
cout<<"The equation has single root x = "<<-c/b<<endl;
else
{
disc=pow(b,2.0) -4*a*c;
if(disc>0.0)
{
disc=sqrt(disc);
root1=(-b + disc)/(2*a);
root2=(-b - disc)/(2*a);
cout<<"The two real roots are"<<root1<<"and"<<root2<<endl;
}
else if(disc<0.0) {
real = -b/(2*a);
imag =sqrt(-disc)/(2*a);
cout << "Both roots are imaginary.The 2 roots are " << endl;
cout << real << "+" << imag << "i" << endl;
cout <<real << "-" << imag << "i" << endl;
}
else
cout<<"Both roots are equal to "<<-b /(2*a)<<endl;
}
return 0;
