此程序在C++和VC++均可使用 程序包括集合交并运算，复制集合，集合子集的判断等-this program in C and Visual C + + can make use of the procedures set pay and operations, reproduction pool, pool subset of judgment

这是一个模拟集合元素的程序,可以对进行和,差运算

两个集合 A，B，依次输入集合中的元素，通过运算求出两个集合的交集-Two sets A and B, followed by input elements in the collection obtained by computing the intersection of two sets
