I'm trying to parse a string with spaces into several strings and store them into a list, which consists of strings without any space. I do not know how long the input of the string will me and I have the following code:

#include <bits/stdc++.h>

#include <sstream>



using namespace std;



vector<string> myWords;

vector<char> myBuffer;



int main() {

    string mySentence;

    getline(cin, mySentence);



    int j = 0;

    for (int i = 0; i < mySentence.length(); i++) {

        if (mySentence[i] != ' ') myBuffer.push_back(mySentence[i]);

        else {

            myWords.push_back(myBuffer);

            myBuffer.clear();

            j++;

        }

    }



    return 0;

}

The error in which I'm getting is at myWords.push_back(myBuffer);. How do I get around this?

The problem is that you are trying to push a std::vector<char> where a std::string is expected. So simply change the type of myBuffer to a std::string:

#include <iostream>

#include <string>



int main() {

    std::string mySentence;

    std::getline(std::cin, mySentence);



    std::vector<std::string> myWords;

    std::string myBuffer;



    for (int i = 0; i < mySentence.length(); i++) {

        if (mySentence[i] != ' ')

            myBuffer.push_back(mySentence[i]);

        else {

            myWords.push_back(myBuffer);

            myBuffer.clear();

        }

    }



    if (!myBuffer.empty()) {

        myWords.push_back(myBuffer);

    }



    // use myWords as needed...



    return 0;

}

That being said, using a std::istringstream would be much simpler, as operator>> reads whitespace-delimited values from a stream for you:

#include <iostream>

#include <string>

#include <sstream>



int main() {

    std::string mySentence;

    std::getline(std::cin, mySentence);



    std::vector<std::string> myWords;

    std::string myBuffer;



    std::istringstream iss(mySentence);

    while (iss >> myBuffer) {

        myWords.push_back(myBuffer);

    }



    // use myWords as needed...



    return 0;

}

Alternatively, let the standard library handle the reading and pushing for you:

#include <iostream>

#include <string>

#include <sstream>

#include <iterator>



int main() {

    std::string mySentence;

    std::getline(std::cin, mySentence);



    std::vector<std::string> myWords;



    std::istringstream iss(mySentence);

    std::copy(

        std::istream_iterator<std::string>(iss),

        std::istream_iterator<std::string>(),

        std::back_inserter(myWords)

    );



    // use myWords as needed...



    return 0;

}
