Rule:  INT#004Checked automatically with code checker

This rule is Obsolete
Synopsis:Always specify the return type of a method/function explicitly
Severity Level:5
Category:Class Interface


Methods or functions, for which no return type is explicitly declared, implicitly receive int as the return type. This can be confusing for a beginner, since the compiler gives a warning for a missing return type. Methods or functions that do not need to return a value should specify void as the return type.
