So once we have the extended Euclidean algorithm our inverse function is trivial to write! Via a chain of relatively easy-to-prove lemmas, if your number type has enough structure in particular, if it has a division algorithm that satisfies some propertiesthen greatest common divisors are well-defined, and the Euclidean algorithm gives us that special linear combination. And using the same trick above in finite fields, we can use the Euclidean algorithm to compute inverses.
Programs and units Chapter3 A program is constructed from source-code modules called units. Each unit is stored in its own file and compiled separately; compiled units are linked to create an application.
In traditional Pascal programming, all source code, including the main program, is stored in.

Borland tools use a project. Each application—or project—consists of a single project file and one or more unit files. To build a project, the compiler needs either a source file or a compiled unit file for each unit.
The program heading specifies a name for the program.
The uses clause lists units used by the program. The block contains declarations and statements that are executed when the program runs.
The IDE expects to find these three elements in a single project. Programs and units Program structure and syntax The following example shows the project file for a program called Editor. Line 1 contains the program heading.
The uses clause is on lines 3 through 6. Lines 10 through 14 contain the block of statements that are executed when the program runs. Finally, the project file, like all source files, ends with a period.
This is, in fact, a fairly typical project file. Project files are generated and maintained automatically, and it is seldom necessary to edit them manually.
It consists of the reserved word program, followed by a valid identifier, followed by a semicolon. The identifier must match the project file name. In the previous example, since the program is called Editor, the project file should be called Editor.
In standard Pascal, a program heading can include parameters after the program name: The program uses clause The uses clause lists units that are incorporated into the program. These units may in turn have uses clauses of their own.
The block The block contains a simple or structured statement that is executed when the program runs. The block can also contain declarations of constants, types, variables, procedures, and functions; these declarations must precede the statement part of the block.
Unit structure and syntax A unit consists of types including classesconstants, variables, and routines functions and procedures. Each unit is defined in its own unit.
A unit file begins with a unit heading, which is followed by the interface, implementation, initialization, and finalization sections. The initialization and finalization sections are optional. A skeleton unit file looks like this: The unit must conclude with the word end followed by a period.
It consists of the reserved word unit, followed by a valid identifier, followed by a semicolon.
For applications developed using Borland tools, the identifier must match the unit file name. Programs and units Unit structure and syntax Unit names must be unique within a project. Even if their unit files are in different directories, two units with the same name cannot be used in a single program.
The interface section The interface section of a unit begins with the reserved word interface and continues until the beginning of the implementation section.
The interface section declares constants, types, variables, procedures, and functions that are available to clients— that is, to other units or programs that wish to use elements from this interface section.
These entities are called public because a client can access them as if they were declared in the client itself. The block of the procedure or function follows in the implementation section.
The interface declaration for a class must include declarations for all class members. The interface section can include its own uses clause, which must appear immediately after the word interface.The program then assigns the string “Hello world!” to the variable MyMessage, and sends the contents of MyMessage to the standard output using the Writeln procedure.
