This is a sample code using symbolic C++.
#include <iostream>
#include "symbolicc++.h"
using namespace std;
int main(void)
{
int i;
Symbolic x("x"), y, z("z");
y = (x + 2)^3;
cout<<" y = "<<y;
for ( i = 0 ; i < 1 ; i++)
{
y = df(y,x);
cout<<" y = "<<y<<endl;
}
return 0;
}
My question : is there any way to make symbolic variables to be input by user ?
If you want to get functions from the user to pass to the program than you might be able to do the following. No guarantee though I am just guessing from the code that you have provided.
string input;
cout << "Enter Equation: ";
getline(cin, input);
Symbolic y(input.c_str());
string input;
cout << "Enter Equation: ";
getline(cin, input);
Symbolic y(input.c_str());
It doesn't realy work, beacuse, the expression is "stored" in input, but is quite useless. If you try to differentiate it, the result is "0".
I have no idea how to define a "function" (Symbolic f) from a string. I've been dealing with this problem since a long time...
Yes. I have read this, downloaded from here only. I gone through the header file of symbolicc++ and found this.
ostream &operator<<(ostream &o,const Symbolic &s)
{ s.print(o); return o; }
So I was thinking is there any way that is there any way to overload >> operator ?
I couldn't find any way, how to take symbolic variables from user during runtime.
