好的,以下是程序的代码:
```
setA = set(input("请输入集合A,元素之间用空格隔开:").split())
setB = set(input("请输入集合B,元素之间用空格隔开:").split())
intersection = setA.intersection(setB)
union = setA.union(setB)
difference = setA.difference(setB)
print("集合A和集合B的交集为:", intersection)
print("集合A和集合B的并集为:", union)
print("集合A和集合B的差集为:", difference)
```
希望这个程序能够帮到你!

编写程序,输入两个集合 seta 和 setb,分别输出它们的交集、并集和差集 seta-setb
这是一个用 Python 实现的程序示例:
```python
seta = set([1, 2, 3])
setb = set([2, 3, 4])
# 交集
print(seta.intersection(setb))
# 并集
print(seta.union(setb))
# 差集 seta-setb
print(seta.difference(setb))
```
输出:
```
{2, 3}
{1, 2, 3, 4}
{1}
```

您好,我可以回答您的问题。以下是程序的代码:
#include <iostream>
#include <set>
using namespace std;
int main()
{
set<int> setA, setB;
set<int> intersection, unionSet, difference;
// 输入 setA 和 setB
int n, m;
cout << "请输入 setA 的元素个数:";
cin >> n;
cout << "请输入 setA 的元素:";
for (int i = ; i < n; i++) {
int x;
cin >> x;
setA.insert(x);
}
cout << "请输入 setB 的元素个数:";
cin >> m;
cout << "请输入 setB 的元素:";
for (int i = ; i < m; i++) {
int x;
cin >> x;
setB.insert(x);
}
// 计算交集
set_intersection(setA.begin(), setA.end(), setB.begin(), setB.end(), inserter(intersection, intersection.begin()));
cout << "交集为:";
for (auto it = intersection.begin(); it != intersection.end(); it++) {
cout << *it << " ";
}
cout << endl;
// 计算并集
set_union(setA.begin(), setA.end(), setB.begin(), setB.end(), inserter(unionSet, unionSet.begin()));
cout << "并集为:";
for (auto it = unionSet.begin(); it != unionSet.end(); it++) {
cout << *it << " ";
}
cout << endl;
// 计算差集
set_difference(setA.begin(), setA.end(), setB.begin(), setB.end(), inserter(difference, difference.begin()));
cout << "setA-setB 差集为:";
for (auto it = difference.begin(); it != difference.end(); it++) {
cout << *it << " ";
}
cout << endl;
return ;
}
