why won't the sort() function work although I've included algorithm header

Question

#include<iostream>
#include<string>
#include<vector>
#include<algorithm>
using namespace std ;

int main(){ vector<string>words ;
for(string word;cin>>word;){
words.push_back(word);
}
for(string x:words)
cout<<x<<",";
sort(words);
for(string x: words)
cout<<x<<", ";
}

hello I'm new to this app and to programming, I'm using cxxdroid to code c++ however the sort() will give an error with the compiler

such as
<stdin>:13:1: error: no matching function for call to 'sort'
sort(words);
^~~~
/data/user/0/ru.iiec.cxxdroid/files/bin/../lib/gcc/aarch64-linux-android/4.9.x/../../../../include/c++/4.9.x/algorithm:4122:1: note: candidate function template not viable: requires 3 arguments, but 1 was provided

Answer 1

sort(words.begin(),words.end());

Answer 2

/*
bonus: sort with lambda expression, reverse.
*/
#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;

int main()
{
vector<string> words{
"park","zoo","arcade"};
cout<<"words:\n";
for(auto i: words)
cout<<i<<' ';
cout<<'\n';

cout<<"\nsort:\n";
sort(words.begin(),words.end());
for(auto i: words)
cout<<i<<' ';
cout<<'\n';

cout<<"\nsort descending with lambda expression:\n";
sort(words.begin(),words.end(),[](const string &a, const string &b){return a>b;});
for(auto i: words)
cout<<i<<' ';
cout<<'\n';

cout<<"\nreverse:\n";
reverse(words.begin(),words.end());
for(auto i: words)
cout<<i<<' ';
cout<<'\n';
}
