2. Assembly Language Assembly Language Is a Programming Language That Is Very Similar to Machine Language, but Uses Symbols Instead of Binary Numbers
2. Assembly Language Assembly Language is a programming language that is very similar to machine language, but uses symbols instead of binary numbers. It is converted by the assembler into executable machine- language programs. Assembly language is machine-dependent; an assembly program can only be executed on a particular machine. 2.1 Introduction to Assembly Language Tools Practical assembly language programs can, in general, be written using one of the two following methods: 1- The full-segment definition form 2- The simplified segment definition form In both methods, the source program includes two types of instructions: real instructions, and pseudo instructions. Real instructions such as MOV and ADD are the actual instructions that are translated by the assembler into machine code for execution by the CPU. Pseudo instructions, on the other hand, don’t generate machine code and are only used to give directions to the assembler about how it should translate the assembly language instructions into machine code. The assembler program converts the written assembly language file (called source file) into machine code file (called object file). Another program, known as the linker, converts the object file into an executable file for practical run. It also generates a special file called the map file which is used to get the offset addresses of the segments in the main assembly program as shown in figure 1. Other tools needed in assembling coding include a debugger, and an editor as shown in figure 2 Figure 2. Program Development Procedure There are several commercial assemblers available like the Microsoft Macro Assembler (MASM), and the Borland Turbo Assembler (TASM). -

C++ Builder 2010 Professional Getting Started
C++ Builder 2010 Professional Getting started. Kjell Gunnar Bleivik: http://www.kjellbleivik.com/ October 18. 2010. Fixed broken link. Status: Most probably finished. Look at the date in case more should be added. Follow me on Twitter and join my C++ Builder group on Facebook: Twitter: http://twitter.com/kbleivik FaceBook: http://www.facebook.com/people/Kjell-Gunnar-Bleivik/1244860831 Mini network: http://www.digitalpunkt.no/ 1. Installing C++Builder 2010, the help system etc. I ordered my upgrade of Borland C++ Builder Prosessional 2010 on September 21 2009 so I could choose an additional free product. I choose Delphi PHP 2.0, since I am fairly used to PHP. In order to install C++ Builder 2010, I had to upgrade my 2009 version. I have made an 2009 and 2010 upgrade shortcut on my desktop. You should find your upgrade program: | your start menu or in | the all program category | CodeGear RAD studio 2009 | Check for updates | Program | When finished upgrading the 2009 Builder, I could run the C++ Builder 2010 Setup program. In addition, I installed the additional first three programs that I also find in the Install Folder. Look at the screendumps below, so you get it correct. • Help_Setup Program • dbpack_setup Program • boost_setup Program • Additional_Products HTML document. • ERStudio_Interbase HTML document 2. Getting started with C++ Builder 2010 Professional. If you learn to use the welcome page efficiently, that may be all you need. On the “documentation” menu, you should start with, yes “Getting started” and then “RAD Studio Help” and so on. As an example click: | Documentation | … and try to locate this http://docs.embarcadero.com/products/rad_studio/ page with Wiki pages, PDF documents, zipped code examples for download, PDF documents since C++Builder 6 (scroll down to the bottom) and CHM http://en.wikipedia.org/wiki/Microsoft_Compiled_HTML_Help files. -

Lab # 1 Introduction to Assembly Language
Assembly Language LAB Islamic University – Gaza Engineering Faculty Department of Computer Engineering 2013 ECOM 2125: Assembly Language LAB Eng. Ahmed M. Ayash Lab # 1 Introduction to Assembly Language February 11, 2013 Objective: To be familiar with Assembly Language. 1. Introduction: Machine language (computer's native language) is a system of impartible instructions executed directly by a computer's central processing unit (CPU). Instructions consist of binary code: 1s and 0s Machine language can be made directly from java code using interpreter. The difference between compiling and interpreting is as follows. Compiling translates the high-level code into a target language code as a single unit. Interpreting translates the individual steps in a high-level program one at a time rather than the whole program as a single unit. Each step is executed immediately after it is translated. C, C++ code is executed faster than Java code, because they transferred to assembly language before machine language. 1 Using Visual Studio 2012 to convert C++ program to assembly language: - From File menu >> choose new >> then choose project. Or from the start page choose new project. - Then the new project window will appear, - choose visual C++ and win32 console application - The project name is welcome: This is a C++ Program that print "Welcome all to our assembly Lab 2013” 2 To run the project, do the following two steps in order: 1. From build menu choose build Welcome. 2. From debug menu choose start without debugging. The output is To convert C++ code to Assembly code we follow these steps: 1) 2) 3 3) We will find the Assembly code on the project folder we save in (Visual Studio 2012\Projects\Welcome\Welcome\Debug), named as Welcome.asm Part of the code: 2. -
Practical C++ Programming Copyright 2003 O'reilly and Associates Page 1 I/O Packages
Chapter - 16 File Input/ Output Practical C++ Programming Copyright 2003 O'Reilly and Associates Page 1 I/O Packages There are 3 different I/O packages available to the C++ programmer: • The C++ streams package. This package is used for most I/O. • The unbuffered I/O package. Used primarily for large file I/O and other special operations. • The C stdio package. Many older, C-- programs use this package. (A C-- program is a C program that has been updated to compile with a C++ compiler, but uses none of the new features of the new language.) This package is useful for some special operations. Practical C++ Programming Copyright 2003 O'Reilly and Associates Page 2 C++ I/O C++ provides four standard class variables for standard I/O. Variable Use std::cin Console in (standard input) std::cout Console output (standard output) std::cerr Console error (standard error) std::clog Console log Normally std::cin reads from the keyboard, and std::cout, cerr, and clog go to the screen. Most operating systems allow I/O redirection my_prog <file.in my_prog >file.out Practical C++ Programming Copyright 2003 O'Reilly and Associates Page 3 File I/O File I/O is accomplished using the <fstream.h> package. Input is done with the ifstream class and output with the ofstream class. Example: ifstream data_file; // File for reading the data from data_file.open("numbers.dat"); for (i = 0; i < 100; ++i) data_file >> data_array[i]; data_file.close(); Open can be consolidated with the constructor. ifstream data_file("numbers.dat"); The close will automatically be done by the destructor. -
