This is how it was on the Microsoft site, with me just tweaking the SPSite and SPWeb since these might vary from environment to environment and it helps not to have to hard-code these:

using (SPSite oSiteCollection = new SPSite(SPContext.Current.Site.Url))
{
    using (SPWeb oWeb = oSiteCollection.OpenWeb(SPContext.Current.Web))
    {
        SPList oList = oWeb.Lists["Announcements"];
        // You may also use 
        // SPList oList = oWeb.GetList("/Lists/Announcements");
        // to avoid querying all of the sites' lists
        SPListItem oListItem = oList.Items.Add();
        oListItem["Title"] = "My Item";
        oListItem["Created"] = new DateTime(2004, 1, 23);
        oListItem["Modified"] = new DateTime(2005, 10, 1);
        oListItem["Author"] = 3;
        oListItem["Editor"] = 3;
        oListItem.Update();
    }
}
