quadratic equation solver

[Ryan Parker]

Just finished some new code and wanted to share it because mabye some people would like it, Here it is. It solves quadratic equations and puts this (x+a)(x+b) in standard form for solving.


#include <iostream>
#include <math.h>
using namespace std;
//MASS ALOCATION!!! LOL
float x1plus;
float x2plus;
int one;
int two;
int dude;
int x;
int a;
int b;
int c;
double power;
double bob;
double dis;
double joemama;
int bottom;
double answer1;
double answer2;
int main()
{
one = 1;
two = 2;
cout << "Quadratic Equation Solver by Ryan Parker\n" << endl;
cout << "type 1 and press enter if your problem is in standard form" << endl;
cout << "type 2 if its in (x+a)(x+b) form." << endl;
cin >> dude;
if (dude == 1)
{
for (x = 0; x <= 40; x++)
{
cout << "ax^2+bx+c" << endl;
cout << "imput the 'a' variable: " << endl;
cin >> a;
cout << "imput the 'b' variable: " << endl;
cin >> b;
cout << "imput the 'c' variable: " << endl;
cin >> c;
bottom = 2*a;
power = pow (b,2);
bob = 4*a*c;
dis = power - bob;
cout << "This is the Discriminenet: " << dis << endl;
if (dis < 0)
{
cout << "discriminent is less than zero, Answer is imaginary!" << endl;
cout <<"\n" << endl;
cout <<"\n" << endl;
}
else
{
joemama = sqrt(dis);
answer1 = (-b+joemama);
answer2 = (-b-joemama);
cout << "x=" << answer1 / bottom << endl;
cout << "x=" << answer2 / bottom << endl;
cout << "\n" << endl;
cout << "\n" << endl;
}
}
}
else if (dude == 2)
{
for (x = 0; x <= 40; x++)
{
cout << "imput the number after x1" << endl;
cin >> x1plus;
cout << "imput the number after x2" << endl;
cin >> x2plus;
cout << "in standard form: x^2+" << x1plus+x2plus << "x+" << x1plus*x2plus << endl;
}
}
else
{
cout << "come on, only 1 or 2";
}
return 0;
}

Thanks for sharing, you may want to put it in the source code sub category of the articles http://www.cplusplus.com/articles/sourcecode/ ...
But please use code tags, thank you :)
