push_back not working in loop

[coolcoder3412]

In the code below, I tried to let the user input text, and it would output the first word. However, whenever I try the program to input the text, it doesn't output anything.

//code below
#include <iostream>
#include <vector>

using namespace std;

int main()
{
vector<string> words;
for(string winput; cin>>winput; )
words.push_back(winput);

cout << words[0];
}

It most likely doesn't reach the cout statement. That's because there is no obvious way to exit from the loop. For example, below, the loop ends when the user types "stop".

#include <iostream>
#include <vector>
#include <string>

using namespace std;

int main()
{
    vector<string> words;
    
    for(string winput; cin>>winput && winput != "stop"; )
        words.push_back(winput);

    cout << words[0];
}
