You can provide default values for function parameters. For example: #include <iostream> using namespace std; int a = 1; int f(int a) { return a; } int g(int x = f(a)) { return x; } int h() { a = 2; { int a = 3; return g(); } } int main() { cout << h() ...

A union member cannot be of a class type that has a nontrivial constructor. Like all functions, a constructor can have default arguments. They are used to initialize member objects. If default values are supplied, the trailing arguments can be omitted in the expression list of the constructor...

2. Member Functions Member functions are functions which are defined inside a class or an object. class User(val firstName: String, val lastName: String) { // Member function fun getFullName(): String { return firstName + " " + lastName } } Member functions are called on the objects...
