Algorithm problem

[smurf12125]

I have a algorithm bulit but I have errors and don't know why I am getting them.

#include <iostream>
#include <string>
#include <fstream>
#include <iomanip>
#include <algorithm>
#include <vector>
using namespace std;
typedef std::vector <std::string> StringArray;
int main()
{
cout << "This program is a database for storing information." << endl;
    ofstream myfile;
    myfile. open ("data.txt", ios::app);
cout << "Please input what you want to store." << endl;
 StringArray s;
    std::string inString;
    for (int i = 0, i < 5; i++ ;); /// line 17
    s.push_back(inString);
{   getline (cin, inString);
myfile << inString << endl;
}
    sort (s.begin(), s.end(), greater<int>());
    myfile. close ();
system("pause");
return 0;
}

I get the errors

What is going on here? I've been researching this for a couple days and can't figure out whats going wrong.
