print line in reverse using stack

[ptg]

im trying to write a program inputs some words and uses a stack object to print the line in reverse. when i run my program it gives me the word the right way not reversed. for ex: hello there it gives me hello there
what am i doing wrong?

#include <iostream>
#include <stack>
#include <string>
using namespace std;

int main() {

    stack<string> allwords; // stack of all words
    string word;            // input for words.

	cout << "enter some words: ";
    getline(cin, word);
    allwords.push(word);
    
    while (!allwords.empty()) {
       cout << allwords.top() << endl;
       allwords.pop();         
    }
    return 0;
}
