Simpson’s Rule: Integral approximation

This program calculates the integral approximation of a function using Simpson’s rule. Enter “A” (The lower limit of integration), “B” (The upper limit of integration), “N” (The given number of subintervals), and “Function” (The function for which the program will use Simpson’s Rule to approximate the integral) and the program will automatically calculate the integral approximation. The program stores the answer in the variable “X”. Remember the Simpson’s Rule is only valid when n is even. The program will stop if n is odd.
