将一句话里的单词进行倒置

实现一句话倒置：如下所示

//输入
I am a boy.
//输出
boy. a am I

思路：用栈的后进先出的思想

#include
#include
#include
#include
using namespace std;

int main(){
	stack sstack;
	string line, word;
	getline(cin, line);
	istringstream stream(line);
	while (stream >> word) {
		sstack.push(word);
	}
	while (!sstack.empty()) {
		cout << sstack.top() << " ";
		sstack.pop();
	}
	return 0;
}
