Write a function that returns the value of the polynomial a0 + a1x + a2x^2 +...+ anx^n for a given x. The function prototype is double poly( doublea[], double x, int n); where the coefficients of the polynomial are stored into a and n represents its degree. Write a C program that reads the degree of a polynomial, its coefficients, and a value (e.g., x) and uses the function to calculate the value of the polynomial. Assume that the maximum degree is 100.
