cand sterg if (i == 3) meniu3(); si int meniu3() dau run si merge.

Putin complex din cate vad (imi cer scuze daca intr-adevar este). Dar cred ca rezultatul este cea ce cauti.

Atentie: Necesita un compiler recent. GCC 4.7+ sau VS 2013+ (posibil sa functioneze si pe un compiler mai vehi dar nu garantez)
