Introduction to Computer Programming

Computer programming is an essential part of the

work of many scientists and engineers.

This semester we will teach theC++ Programming Language which

is not easy to learn (compared to Fortran)

Is a huge language with a lot of technical details

is good at system and application programming

is mostly prefered by engineers and young programmers!

is widely used in the software industry

We will concentrate on only a very basic/minimal subset of C++

Computer Labs

We will learn C++ using the Dev-C++ compiler under Windows; you may also use Linux , e.g. Ubuntu, gul4.bim...

Every week you should write a few programs yourselfin the BIM lab (and more in your free time).

In the BIM Computer Labs your programs will be deleted when the computer reboots. So you need

to save them on a flash drive or on the internet.

DO NOT FORGET TO BRING

YOUR LAPTOP or FLASH DISK WITH YOU

Sayfa 9

The Computer

See http://en.wikipedia.org/wiki/Computer

A computer is a machine that manipulates data according to

a set of instructions.

The first computers were developed in 19401945, they were very large in size!

Modern computers arebased on integrated circuits

making them very fast

and small in size.

Sayfa 11

Parts of a Digital Computer

A computer can be divided into two main parts:

Hardware and Software.

Hardware (=Donanm)

See http://en.wikipedia.org/wiki/Hardware

Hardware is the electronic and

mechanical parts of the computer.

- Storage Units

- Input Units

- Output Units

- Process Units

Sayfa 12


Storage Units

These are used in both input and output of data:

HDD (Hard Disk Drive)

high capacity, relatively cheap, slow.

RAM (Random Access Memory)

low capacity, expensive, but very fast.

Others:

Flash memory (memory cards, USB flash drives), CD, DVD...

Sayfa 13


Input Units

Used for input of data:

Keyboard,

Mouse

Touch screen/pad

RAM,

HDD

Flash memory

Sayfa 14


Output Units

Used for output of data:

Monitor

Printer

Speaker

RAM

HDD

Flash Memory

Sayfa 15


Process Units

CPU: Central Processing Unit

This coordinates the operation of computer system

and performs arithmetic logic operations.

Input unit CPU Output unit

Sayfa 16


A program is input from an HDD(1) and executed in RAM(2).

Data is input from a keyboard(3) which is again stored in RAM(4).

The CPU operates on the program and data in RAM(5) and

outputs results to the HDD(6) as well as the monitor(7).

This is all controlled by the CPU requiring only basic

data flow instructions from the programmer.

Sayfa 17


Software (=Yazlm)

See http://en.wikipedia.org/wiki/Software

Software consists of programs loaded from storage units.

The programs execute on the computer hardware forming,

for example,

Operating System (OS)

Compilers

Application Programs

Sayfa 18


Operating System (OS)

The OS is a program written to interface between the

computer and its user. All other software runs under the OS.

Examples are:

Miscrosoft Windows (XP, Vista, 7)

Linux (e.g. Redhat, Ubuntu, Pardus)

Mac OS X.

These are all created using C++

Sayfa 19


Compilers

See http://en.wikipedia.org/wiki/Compiler

Many programming languages require a compiler to

translate the statements of program written in a high level

language into a low level language (machine code).

Examples are:

Fortran

C, C++

Java

Pascal

Basic.


Sayfa 20


Application Programs

These are (usually compiled) programs written to perform

a specific task.

Examples are:

Microsoft Word

AutoCAD

Mozilla Firefox....
