Question

I am compiling with an old software TurboC++ 4.5(1995) and I am having some errors. Can anyone help?

#include<iostream.h>
#include<math.h>

void cal_root(int,int,int,float&,float&);
void main()
{
  float root1=0,root2=0;
  int a,b,c;
  cout<<"Enter the three co-efficients of quadratic equation with spaces.\n";
  cin>>a>>b>>c;
  cal_root(a,b,c,root1,root2);
  cout<<"The roots for given Quadratic Equation are "<<root1<<" & "<<root2<<".";
}
void cal_root(int a,int b,int c,float& root1,float& root2)
{
  root1=-b+(sqrt((b*b)-4ac))/(2a); //error here
  root2=-b-(sqrt((b*b)-4ac))/(2a); //error here
}

I’m getting the following error:
Function call missing ) in function cal_root(int, int, int, float&, float &)
at lines 16 and 17

You’re not in a math class, you have to write out multiplications explicitly:

4ac -> 4*a*c
2a -> 2*a
