3.3 in progress

/*Write a class IntSet for modeling sets of integers in the range 0 through 99. A set should be represented internally as an array of type bool: The ith  array element will be true whenever integer i is in the set and will be false whenever integer i is not in the set. Include a no-argument constructor that initializes a set to the so-called “empty set,” i.e., a set whose array representation contains all false values.The program should allow for up to ten sets to be created during a given program run. Use any stand-alone functions you feel necessary.*/
