Need help with this C programming assignment using propositional calculus concepts:

L 0verView For this assignment, you're going to write a C program to operate on sets. Our universe of elements consists of all (normal, printable, non-whitespace) single characters that can be entered from the keyboard (a-z, A-Z, 0-9 and punctuation) Your program should prompt the user for the elements of the first set (called A): the user enters the elements, followed by. Do the same for the second set (B). Then print the following information: . The elements of A in the usual format: fe1, e2,..., en The elements of B The cardinality of A and B 2 Details You should prompt the user for their two input strings Remember, a set cannot contain more than one copy of an element. If the user enters an element twice, it should only appear in the set once. . Ignore whitespace (use ctype's "isspace)" function), but treat other characters as elements of the set. Remember to ignore any trailing newlines in vour input the empty set is a valid set
