Single line comment type fncname(type1, type2, ); type fncname(type1 name1, type2 name2, ) Structure type definition type name[rdim1][cdim2]; type *name type *f() { } Determine size in bytes name. member name->member (type) sizeof typedef struct. Unary and assignment operators evaluated right-to-left, all others left-to-right.
