What is the difference between overloaded functions and overriding functions in c
Keyword No keyword applied during overloading. Function which is to be overridden is preceded by keyword 'virtual', in the base class. Distinguishing factor Number or type of parameter differs which determines the version of function is being called. Which class's function is being called by the pointer, is determined by, address of which class's object is assigned to that pointer. Defining pattern Function are redefined with same name, but different number and type of parameter.
Function is defined, preceded by a keyword 'virtual' in main class and redefined by derived class with out keyword. Time of accomplishment Compile time.
Run time. Virtual function can be overridden. Destructor Destructor cannot be overloaded. It is required when the derived class adds information to the same member function of the base class. In function overloading, function signature should be different for all the overloaded functions. Overridden functions must have the very same name and the same number of arguments. In other words, function signatures must be the same.
Overloading yields appropriate results, almost every time depending on the skill of programmer and the real-time application. Table of Contents. Save Article. Improve Article. Like Article.
