Thread: remove whitespace program won't work

The program is supposed to erase all whitespace and all chars past the whitespace from a string, but it just hangs the terminal.

Code:

#include<iostream>
#include<string>
#include<string.h>
#include<vector>
#include<algorithm>
#include<cmath>


#include<sstream>
#include<fstream>
#include<list>
#include<numeric>
#include<map>
#include<iterator>


void removespaces(vector<string>& v){
    for(int i=0; i<v.size(); ++i){
        string::iterator it=find(v[i].begin(),v[i].end(),' ');
        if(it!=v[i].end()){
            v.push_back(v[i]);
            it=find(v[i].begin(),v[i].end(),' ');
            v[i].erase(it,v[i].end());
        }
    }
}
int main()
{


    vector<string> words;




    words.push_back("aa bb");


    removespaces(words);


    for(auto& f:words)
        cout<<f<<'\n';


}
