Member Avatar for new programer

Hello all,

As my name indicates, I am a new programmer. I was doing a program which calculates the roots of a quadratic equation but unfortunately there seems to be something wrong as it ignores my if statements!


Please take a look at my code and I'd appreciate your help

# include <iostream>
# include <cmath>

using namespace std;
int main()
{
	double a, b, c, x, delta, f;
	a=0;
	b=0;
	c=0;

	
	cout << "Welcome to The Real Roots Calculator" << endl;
	cout << "Please Enter a, b, c seperated by a space. Then press return" << endl;
	
	cin >> a; 
	cin >> b;
	cin >> c;

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

	f = sqrt(delta);

	if (delta > 0)
	{  cout << "The roots are:" << endl;
	   cout << "x1 =" << ((-1*b) + f)/(2*a) << endl;
	   cout << "x2 =" << ((-1*b) - f)/(2*a) << endl; }
	
	  else if (delta = 0) 
	  { cout << "There is one Unique Zero" << "x =" << -b /(2*a) << endl; }

			 else if (delta < 0)
			 {  cout << "Sorry! There are no real roots for this equation" << endl; }

	
 cout << "Thank you for using this program" << endl;

	return 0;
}

else if ( delta == 0 ) // compare, don't assign!

Yeah, thats a common mistake (i think we all made that one when we were starting out) :)
