quadratic equation

Question

Can any one solve quadratic equation using do while loop in c++ language

Answer 1

We are not writing code for people here.

But we do assist you, if you show us your honest attempt!

Answer 2

I am out
Dont wanna copy&paste to see whats wrong.
Wake me up, if the code is available on SL playground

Answer 3

In addition to aforementioned issues, I found:
- missing "using namespace std;"
- clrscr() not supported (remove it)
- getch() at end is useless in SoloLearn's batch run environment (remove it)
- missing ; after do/while statements

At run time it falls into an infinite loop when I enter 1 6 9 for a b c.

Answer 4

Yes we can

Answer 5

Pls do this

Answer 6

Can you tell us what sort of problems you ran into with your code?

(I see a few capitalized dos and whiles.)

Answer 7

Void main (void) is not accepting

Answer 8

That's normal. Have you tried int main?

Answer 9

and if you have a look inti your first prog here?

Answer 10

Int main is also not working

Answer 11

#include<iostream>
#include<math.h>
void main(void)
{
clrscr();
double a,b,c,d,r1,r2; //ax^2+bx+c , d=b*b-4ac
cout<<"Enter value of a"<<endl;
cin>>a;
cout<<"Enter value of b"<<endl;
cin>>b;
cout<<"Enter value of c"<<endl;
cin>>c;
d=b*b-4*a*c;

Do{
cout<<"Real root"<<endl;
r1=4*a*c/(2*a*(-b+sqrt(d)));
r2=4*a*c/(2*a*(-b-sqrt(d)));
cout<<"Root 1 "<<r1<<"Root 2 "<<r2<<endl;
}
While(d>0)

Do{
cout<<"Same root"<<endl;
r1=4*a*c/(2*a*(-b+sqrt(d)));
r2=4*a*c/(2*a*(-b-sqrt(d)));
cout<<"Root 1 "<<r1<<"Root 2 "<<r2<<endl;
}
While(d==0)
Do{
cout<<"image"<<endl;
r1=4*a*c/(2*a*(-b+sqrt(d)));
r2=r1;
cout<<"Root 1 "<<r1<<"Root 2 "<<r2<<endl;
}while(d<0)
getch () ;
}
