Your returning the function main() to an integer???
Listen to what alphaoide said, main will return 0.
Also, you only need 1 include. <iostream> (drop the .h, they are depricieted)
Code:
#include <iostream>
using namespace std;
int main()
{
int watdoyousee;
cout <<"filler V0.1 unregistert version\n";
cout <<"\n\n\n\n\n";
cout <<"1.unpack\n";
cout <<"2.pack\n";
cin>>watdoyousee;
if (watdoyousee == 1)
{
cout <<"dombo\n\n";
}
else if (watdoyousee == 2)
{
cout <<"goedso\n\n";
}
else
{
cout << "Unknown option '" << watdoyousee << "'\n";
}
return 0;
}
