Take it easy on me I should know this but I haven't had my private long. I was enroute today to a small non towered field right beside some class C airspace. I contacted the approach controller 30 miles out or so just to get traffic advisories yada yada. After she said radar contact she said contact me 120.10 so I asknowledged and did that. On that frequency she said 570 contact cessna 7k4 (don't remember the exact tail number) on the approach frequency I was previously on. So I switched back over and tried to contact this aircraft twice, to which it never answered. I was just wondering what the purpose of me trying to contact another aircraft while on the approach frequency? I would think if I was close to traffic she would say traffic 9oclock 3miles whatever, I didnt really follow as to what the purpose of me contacting this aircraft was. If I would have made contact what would I have said back, the tower just wanted me to contact you, where you eating lunch?
