C Program to evaluate the given polynomial P(x)=AnXn + An-1Xn-1 + An-2Xn-2+… +A1X + A0, by reading its coefficents into an array.

Write a C program to evaluate the given polynomial P(x)=AnXn + An-1Xn-1 + An-2Xn-2+… +A1X + A0, by reading its coefficents into an array.A Polynomial is a mathematical expression involving a sum of powers in one or more variables multiplied by coefficients. Read more about C Programming Language .
