Grammar Structure 3: Evaluation of Functions

 
Execution rule for functions:

 

 

-
Evaluate the function by its arguments, and if the arguments contain expressions, evaluate those expressions first.

-
The output of functions is called the returned value.

+
A function’s input arguments, when there’s more than one, can be specified by:

+
    
+
  • The order the input given: pow(2, 3) is different than pow(3, 2).
    • 
+
  • The name of the input argument: pow(base=2, exp=3).
    • 
+

If the arguments contain expressions, evaluate those expressions first!
