Answer:
are automatically passed by reference.
Explanation:
A parameter can be defined as a value that can be passed to a function. Thus, a parameter refers to a value that must be passed into a function, subroutine or procedure when it is called.
This value can be passed to a function either by reference or by value.
This ultimately implies that, parameter variable stores information which is passed from the location of the method call directly to the method that is called by the program.
Basically, parameters can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function.
In Computer programming, an array can be defined as data structure which comprises of a fixed-size collection of variables each typically holding a piece of data and belonging to the same data type such as strings or integers.
This ultimately implies that, when a programmer wishes to store a group of related data (elements) of the same type, he or she should use an array.
A character positions in arrays start counting with the number 0 not 1.
Hence, an array uses a zero-based indexing and as such the numbering or position of the characters (elements) starts from number 0. Thus, the first character (element) in an array occupies position zero (0), the second number one (1), the third number two (2) and so on.
Generally, arrays of structures are automatically passed by reference through the use of a REPLICATE function.
