- Penggunaan fungsi hamper mirip dengan procedure. Penulisan Fungsi Konsep fungsi di dalam bahasa pascal mirip dengan konsep fungsi di dalam matematika dimana fungsi digunakan untuk menghitung nilai berdasarkan nilai masukan. Berikut adalah contoh program menggunakan fungsi: Perhatikan bagaimana fungsi ini digunakan.
- BAB 2 TIPE DATA, NILAI, INPUT DAN OUTPUT 2.1 TUJUAN PRAKTIKUM 2.1.1 Mengetahui dan memahami pengunaan tipe-tipe data dasar pada pascal 2.1.2.
Why OOP?Suppose that you want to assemble your own PC, you go to a hardware store and pick up a motherboard, a processor, some RAMs, a hard disk, a casing, a power supply, and put them together. You turn on the power, and the PC runs. You need not worry whether the CPU is 1-core or 6-core; the motherboard is a 4-layer or 6-layer; the hard disk has 4 plates or 6 plates, 3 inches or 5 inches in diameter; the RAM is made in Japan or Korea, and so on. You simply put the hardware components together and expect the machine to run. Of course, you have to make sure that you have the correct interfaces, i.e., you pick an IDE hard disk rather than a SCSI hard disk, if your motherboard supports only IDE; you have to select RAMs with the correct speed rating, and so on. Nevertheless, it is not difficult to set up a machine from hardware components.Similarly, a car is assembled from parts and components, such as chassis, doors, engine, wheels, brake and transmission. The components are reusable, e.g., a wheel can be used in many cars (of the same specifications).Hardware, such as computers and cars, are assembled from parts, which are reusable hardware components.How about software?
Byte adalah tipe data numeric terkecil dalam bahasa pascal yang merupakan bilangan bulat. Data ini menempati memori komputer sebesar 1 byte ( merupakan susunan dari 8 bit bilangan biner ) sehingga rentang bilangannya berada antara 0 hingga 255.

Can you 'assemble' a software application by picking a routine here, a routine there, and expect the program to run? The answer is obviously NO! Unlike hardware, it is very difficult to 'assemble' an application from software components.
Since the advent of computer 70 years ago, we have written tons and tons of programs and routines. However, for each new application, we have to re-invent the wheels and write the program from scratch!Why re-invent the wheels? Why re-writing codes? Can you write better codes than those codes written by the experts?
Traditional Procedural-Oriented languagesTraditional procedural-oriented programming languages (such as C, Fortran, Cobol and Pascal) suffer some notable drawbacks in creating reusable software components:. The procedural-oriented programs are made up of functions.
Pascal If Statement Multiple Conditions
Functions are less reusable. It is very difficult to copy a function from one program and reuse in another program because the function is likely to reference the global variables and other functions. In other words, functions are not well-encapsulated as a self-contained reusable unit. The procedural languages are not suitable of high-level abstraction for solving real life problems.
Pascal Function
For example, C programs uses constructs such as if-else, for-loop, array, method, pointer, which are low-level and hard to abstract real problems such as a Customer Relationship Management (CRM) system or a computer soccer game.The traditional procedural-languages separate the data structures (variables) and algorithms (functions).
