When a function parameter has a nullable type, e.g., parameter ``++param++`` in ``++f(?int param)++``, it must be explicitly provided in every function call. A nullable-type parameter has no default value.


== Noncompliant Code Example

----
function f(?int param) {}
f();

== Compliant Solution

----
function f(?int param) {}
f(0);
