Arrays in Delphi allow us to refer to a series of variables by the same name and to use a number (an index) to tell them apart.
Here's an example integer array that can hold up to 7 (integer) values. Note: this is a fixed-size static Delphi array declaration.
Arrays as Function Return Types
In Delphi, functions are routines that return a value.
When you want a function to return an array type variable, you might be tempted to use the next declaration:
When you try to compile this code, you'll get the next compile-time error: Pascal Error E2029 Identifier expected but 'ARRAY' found.
Obviously, when you declare functions that will return array value, you cannot include index type specifiers return declaration.
In order to allow a function to return an array value, you first need to create a custom array type, then use it as a return function type:
Arrays as Method/Routine Properties
Similar to using arrays as function return types, when you declare routines that take array parameters, you cannot include index type specifiers in the parameter declarations.
