For non-OOP languages, a custom routine is a function, procedure, or subroutine and for pure OOP languages, a custom routine is a class method. Hybrid languages (both non-OOP and OOP) combine both.

C++:  C++ is a hybrid language and as such offers global functions and class methods. A function must come before it's usage or you can prototype the function. Syntax Example: void sayHello(string pName) { cout << "Hello " + pName + "\n"; }; int add(int p1, int p2) { int result; result = p1 + p2; return result; };  C++ Custom Routines

PHP:  "Custom Function" function PHP uses functions and loosely typed parameters. Function definitions can come before or after their usage so my preference when mixing PHP in with a mostly HTML page is to put the functions after the </html> tag. Syntax Example: function sayHello($pName) {  echo "Hello " . $pName . "<br>"; } function add($p1, $p2) {  return $p1 + $p2; }  PHP Custom Function (function)

General Info: Inline Routines

Instead of calling a routine, you move the code from the routine itself and expand it in place of the call. In addition to manual inlining, some languages support automatic inlining where the compiler or some other pre-compiler decides when to inline a code routine. Also, some languages allow for developer defined inlining where the developer can suggest and/or force the inlining of a code routine. Inlining can optimize your code for speed by saving a call and return, and parameter management.

Does it support inlining? If so, does it support developer defined inlining? Does it support automatic inlining? Both?

C++:   inline In both Visual C++ and C++Builder, use the inline (standard C++) or __inline (standard C and C++) keywords to suggest to the compiler to inline a routine. Microsoft also offers __forceinline and _inline, Microsoft specific specifiers where __forceinline is a stronger suggestion but still does not always mean the routine will be inlined as well as _inline for backward compatibility. Syntax Example: inline int add(int p1, int p2) { int result; result = p1 + p2; return result; };

Types of overloading include method overloading and operator overloading.

Method Overloading is where different functions with the same name are invoked based on the data types of the parameters passed or the number of parameters. Method overloading is a type of polymorphism and is also known as Parametric Polymorphism.

Operater Overloading allows an operator to behave differently based on the types of values used. For example, in some languages the + operator is used both to add numbers and to concatenate strings. Custom operator overloading is sometimes referred to as ad-hoc polymorphism.

C++:  C++ Overloading Operator - Yes for C++, no for C. Almost all operators can be overloaded for user-defined types Method -  C++ Overloading	PHP:  PHP Operator - No. Method - Syntax Example:    PHP Overloading
