Question

ANSWER PLEASE What are parameters and types of parameters in programming language ?

Answer 1

Default arguments. Some programming languages such as Ada, C++, Clojure, Common Lisp, Fortran 90, Python, Ruby, Tcl, and Windows PowerShell allow for a default argument to be explicitly or implicitly given in a subroutine's declaration. This allows the caller to omit that argument when calling the subroutine.
