Why does carbon not make anion or cation ?

Carbon can form “carbide” compounds with elements that are less electronegative than itself, and be considered an anion in some compounds where it acts as the electron acceptor.
Carbon will also react with halogen elements (fluoride and chloride anions) that are more electronegative than carbon. However, the bond has such a strong covalent character that neither CF4 and CCl4 dissolve to form C4+ cations and F- or Cl- anions. The term “cation” or “anion” should be reserved for the compounds that dissociate into charged particles (monoatomic or polyatomic). CaCO3 dissolves into Ca2+ cations and (CO3)2- anions.

One common source of confusion is to equate the “ionic charge” with “valence”. Carbon can be found in different valence states (CO, CO2, CH4) but these compounds do not dissociate into carbon cations or anions.
