i need a c programm to implement an expression

[raajagopal.v]

hallo comp.lang.c
i am a student trying to sole the bisection method in
numerical methods to find the root of any equation,i need the coding
because i dont know how to implement the polynomial function or
expression that the user gives to execute will any one give the coding
?
please help me

Er, no.

Being a student implies learning. You achieve no such thing by being
given solutions. Go study both your numerical analysis and C textbooks.
If you have any specific questions about your efforts in writing a C
program for bisection method, please do come back here and ask.

please help me

I did, believe me.

In addition to your mathematics textbook, the following resource should
be helpful on the C side. If you use it, do respect the copyright.

In particular, chapter 9 should be useful. After making an attempt at
coding, if you have any problems, do come back here and post your
source.

The programmer converts the user equation for a polynomial to code on an *ad
hoc* basis. It is not intended that you parse some generalized equations by
writing a solver program; that could be a major undertaking. You write:

double f(double x)
{
double temp;
/* code*/
return temp;
}

In case your problem was not what I understood it to be, here are a couple
of useful links. The one that has C++ code is mostly C, except for the I/O.
Try to ignore the I/O or else treat it as magic.

I used this search target:
