so sorry

hello .
I tryed to run your program jlou but I gave this error "declaration syntax error" in the third line (using name...).
I tryed to to make it true but i didnt succeed .
I have borland c++ 3.1 and I must write (.h) in headers name .
my program is too simple , even it is funny . my calculator isn't programable and it is why I wrote this program . here it is :

Code:

code

#include <iostream.h>
#include <conio.h>

int main()
{
float a ;
cin >> a ;
a=a-(a*a*a-a-1)/(3*a*a-1) ;
cout << "ans=" << a ;
getch() ;
return 0;
}
