why does putting the data from a string varible into a string vector put every word into its own place in the vector -C++

Question

im trying to get the data from a string variable and put it into its own place in a string vector but it saves each word as its own point in the vector.

i.e. "buy milk" will result in 0 being buy then 1 being milk not 0 being buy milk.

sorry for not knowing the proper terminology im really new to C++

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

using namespace std;

int main()
{
    string input;
    vector <string> Notes;
    int SaveNoteOnLine = 0;
    string output; //a var needed for specific situations, not used for all output

    cout << "welcome to cmdnotes alpha v1.0\n";
    while (true) {
        cin >> input;
        if (input == "-list") {
            for (int i = 0; i < SaveNoteOnLine; i++) {
                cout << Notes.at(i) << endl;
            }
        }
        else {
            Notes.push_back(input);
            cout << "saved on line " << SaveNoteOnLine << endl;
            SaveNoteOnLine++;
        }
    }
}

Because that's how [`cin >> string`](https://en.cppreference.com/w/cpp/string/basic_string/operator_ltltgtgt) is supposed to work. If your really new, it might be a good idea to find a [good book](https://stackoverflow.com/q/388242/212858). — Useless, Feb 13 '21 at 15:40
thanks for the help, i should probably find a good book about it yeah, is there any alternative to std::cin that doesnt stop at a whitespace character. — tactical waffle, Feb 13 '21 at 15:42
you can use getline(cin,input) to get the string with whitespaces — Rahul Khanna, Feb 13 '21 at 15:42

sorry im a bit dumb, thanks for the book recomendations and help with my code — tactical waffle, Feb 13 '21 at 15:45
Does this answer your question? [std::cin input with spaces?](https://stackoverflow.com/questions/5838711/stdcin-input-with-spaces) — JaMiT, Feb 13 '21 at 16:10

Use getline(cin,input) inplace of cin>>input it will take whitespaces as input
