Write a C program to find all real roots of a polynomial equation of degree n using Bisection method. Note that you can’t define the function as macro or C-function inside your program file. You have to take the polynomial function and degree from user. Also you can’t define the initial interval inside your program . You have to write three different functions
ReadpolynomialFunction() /*use to read the function */
FindInterval() /* use to find initial interval*/
BisectionMethod() /*use to find root */

Did do any thing for that then show your work then only accept for help, If don't do any thing for that, then do hard work before posting your question here.
Best Of Luck.
