Definition - What does Overloading mean? Overloading refers to the ability to use a single identifier to define multiple methods of a class that differ in their input and output parameters. Overloaded methods are generally used when they conceptually execute the same task but with a slightly different set of parameters.
Several restrictions govern an acceptable set of overloaded functions: Any two functions in a set of overloaded functions must have different argument lists. Overloading functions with argument lists of the same types, based on return type alone, is an error.or example, max(double, double) is considered the same as max(double &, double &) . Declaring two such functions causes an error. For the same reason, function arguments of a type modified by const or volatile are not treated differently than the base type for the purposes of overloading.
