The sets class can be used to perform set operations in your programs. It represents set elements as bits in a private array of unsigned long integers. The array size is a defined constant which can be changed to suit your application. The sets class can be used to perform set operations in your programs. It represents set elements as bits in a private array of unsigned long integers. The array size is a defined constant which can be changed to suit your application. The sets class supports the following set operations by means of C++ operator overloading. The sets class can be used to perform set operations in your programs. It represents set elements as bits in a private array of unsigned long integers. The array size is a defined constant which can be changed to suit your application. The sets class supports the following set operations by means of C++ operator overloading: union The union of two sets A, B is the set of all elements which belong to either A or B. In the sets class, the symbol + is the binary union operator: A + B = {x: x is in A -or- x is in B } intersection The intersection of two sets A, B is the set of all elements which belong to both A and B. The symbol * is the binary intersection operator: A * B = {x: x is in A -and- x is in B } example Let A = {1, 2, 3, 4} and B = {3, 4, 5, 6}. Then A + B = {1, 2, 3, 4, 5, 6} A * B = {3, 4} complement In set theory, sets are subsets of a fixed universal set U. In the sets class, U is the set of elements numbered from 1 to MAX_WORDS * WORD_SIZE. In the class declaration file below, the following definitions are made: #define MAX_WORDS 2 #define WORD_SIZE ( 8 * sizeof( unsigned long ) ) These parameters make the range of U, 1 to 64 in sets. To increase or decrease the size of U, change the defined value of MAX_WORDS. The complement of set A is the set of elements belonging to U but not belonging to A. The symbol ~ is the unary complement operator: ~A = {x: x is in U, x is not in A } example Let A = {1, 2, 3, 4} and B = {3, 4, 5, 6}. Then ~A = {5, 6, 7, . . .} ~B = {1, 2, 7, 8, 9, . . .} difference The difference of two sets A, B is the set of all elements which belong to A less those in B. The symbol - is the binary difference operator: A - B = {x: x is in A, x is not in B} example Let A = {1, 2, 3, 4} and B = {3, 4, 5, 6}. Then A - B = {1, 2} It can be shown that A - B = A * ~B. symmetric difference The symmetric difference of two sets A, B is the set of all elements which belong to A or to B, but not both. http://home.att.net/~srschmitt/sets/Sets_class.html http://home.att.net/~srschmitt/sets/Sets_screen.jpg http://home.att.net/~srschmitt/sets/SETSCL10.xml http://home.att.net/~srschmitt/sets/SETSCL10.zip
