weird errors

Hi, I'm new. I've been playing with C++ for a while now. I'm currently a CS major, and taking Intro to Programming for the second time. I've been working on this program (an assignment for class) that takes three employees names, and their respective genders and ages, and puts them in a neat little file. Here's the sourcecode: <lj-cut>

<pre>#include<iostream>
#include<fstream>
#include<iomanip>
using namespace std;

void main()
{
string name = "";
char sex;
int age;
int n = 1; //for the while loop

ofstream fout("emps.txt");

fout<<left<<setw(15)<<"Name"<<right<<setw(5)<<"Age"
<<setw(5)<<"Sex";

while(n<4)
{
cout<<"Enter employee number "<<n<<"'s name: ";
getline(cin,name);
cout<<"Enter employee number "<<n<<"'s age: ";
cin>>age;
cout<<"Enter employee number "<<n<<"'s sex: ";
cin>>sex;


fout<<left<<setw(15)<<name<<right<<setw(5)<<age
<<setw(5)<<sex;

n=n+1;
}

}</pre>

I get the following output when trying to compile:

<tt>--------------------Configuration: p144_num10 - Win32 Debug--------------------

I've no idea what I've done wrong.
