 Pascal requires all variable and function declarations to specify their type explicitly.In traditional C, a type name may be omitted in most contexts and the default type codice_28 (which corresponds to codice_29 in Pascal) is then implicitly assumed (however, such defaults are considered bad practice in C and are often flagged by warnings).C accommodates different sizes and signed and unsigned modes for integers by using modifiers such as codice_30, codice_31, codice_32, codice_33, etc.
