Hello all, I'm at that lovely time in a mathematical learning experience in which you are forced to submit to memorizing the quadratic formula, which is not only despicably confusing but long and painful to work with. I decided to write a program that would do quadratic equations for me, and the final code (debugged and everything) is as follows:

All right, so after compiling and running this I percieve no warnings or errors from the compilers, but after entering the first number and pressing enter, it says that the program has performed an illegal operation. Why?Code:`#include <stdio.h>`

#include <stdlib.h>

#include <math.h>

float a;

float b;

float c;

float d;

float e;

float f;

int main()

{

printf("The format for a quadratic equation is ax^2+bx+c=0.\n");

printf("This should solve a quadratic equation.\n");

printf("Enter the A variable.\n");

scanf("%f",a);

printf("Enter the B variable.\n");

scanf("%f",b);

printf("Enter the C variable.\n");

scanf("%f",b);

if(2*a!=0)

{

d=sqrt(b*b-4*a*c);

e=(-b+d)/(2*a);

f=(-b-d)/(2*a);

printf("X equals %f and %f.\n",e,f);

}

else

{

printf("No real number solution.\n");

}

system("PAUSE");

return 0;

}

Thanks a lot
