Write a program that contains the following functions: The input_fp() function uses an input loop and try/except that accepts only floating-point values and returns the result. The input_int() function uses an input loop and try/except that accepts positive or negative integers and returns the result. The input_index() function takes a list and uses input_int() and try/except to return only valid indexes for the list. The main() function calls each of the others. Call it from the body of the program..
