 Subroutine overloading, commonly known as method overloading in object-oriented programming languages, refers to the ability to create multiple subroutines with the same name but different parameters. This feature allows a programmer to define different ways to call a subroutine based on the types and number of arguments passed. Subroutine overloading, commonly known as method overloading in object-oriented programming languages, refers to the ability to create multiple subroutines with the same name but different parameters.

-Overloaded subroutines have the same name but differ in the type, number, or both type and number of parameters. The appropriate subroutine to call is determined at compile-time based on the arguments provided in the call.+Overloaded subroutines have the same name but differ in the type, number, or both type and number of parameters.
