A problem in the middle of ... !
Hi everyone, I was solving a problem about analysing solutions of quadratic equation, and of corse calculating the solutions. But when I enter the coefficients of equation 2,4,2 ,actually always when first one is bigger than one the results are incorrect. Here is the code:
Code:
#include<iostream>
#include<cmath>
using namespace std;
int main(){
double a,b,c;
cout<<"Enter a : ";
cin>>a;
cin.ignore(1000,'\n');
cout<<"Enter b: ";
cin>>b;
cin.ignore(1000,'\n');
cout<<"Enter c : ";
cin>>c;
double d=b*b-4*a*c;
if(d>=0){
double x1=((-b+sqrt(d))/2*a);
double x2=((-b-sqrt(d))/2*a);
cout<<"x1="<<x1<<" "<<"x2="<<x2<<endl;
}
else{
d=-d;
double re=-b/2*a;
double im=sqrt(d)/2*a;
cout<<"x1="<<"("<<re<<","<<im<<")"<<" "<<"x2="<<"("<<re<<","<<-im<<")"<<endl;
}
return 0;
}
