  • PRE PROCESSOR DIRECTIVES in –C LANGUAGE. 2401 – Course
    PRE PROCESSOR DIRECTIVES IN –C LANGUAGE. 2401 – Course Notes. 1 The C preprocessor is a macro processor that is used automatically by the C compiler to transform programmer defined programs before actual compilation takes place. It is called a macro processor because it allows the user to define macros, which are short abbreviations for longer constructs. This functionality allows for some very useful and practical tools to design our programs. To include header files(Header files are files with pre defined function definitions, user defined data types, declarations that can be included.) To include macro expansions. We can take random fragments of C code and abbreviate them into smaller definitions namely macros, and once they are defined and included via header files or directly onto the program itself it(the user defined definition) can be used everywhere in the program. In other words it works like a blank tile in the game scrabble, where if one player possesses a blank tile and uses it to state a particular letter for a given word he chose to play then that blank piece is used as that letter throughout the game. It is pretty similar to that rule. Special pre processing directives can be used to, include or exclude parts of the program according to various conditions. To sum up, preprocessing directives occurs before program compilation. So, it can be also be referred to as pre compiled fragments of code. Some possible actions are the inclusions of other files in the file being compiled, definitions of symbolic constants and macros and conditional compilation of program code and conditional execution of preprocessor directives.

  • C and C++ Preprocessor Directives #Include #Define Macros Inline
    MODULE 10 PREPROCESSOR DIRECTIVES My Training Period: hours Abilities ▪ Able to understand and use #include. ▪ Able to understand and use #define. ▪ Able to understand and use macros and inline functions. ▪ Able to understand and use the conditional compilation – #if, #endif, #ifdef, #else, #ifndef and #undef. ▪ Able to understand and use #error, #pragma, # and ## operators and #line. ▪ Able to display error messages during conditional compilation. ▪ Able to understand and use assertions. 10.1 Introduction - For C/C++ preprocessor, preprocessing occurs before a program is compiled. A complete process involved during the preprocessing, compiling and linking can be read in Module W. - Some possible actions are: ▪ Inclusion of other files in the file being compiled. ▪ Definition of symbolic constants and macros. ▪ Conditional compilation of program code or code segment. ▪ Conditional execution of preprocessor directives. - All preprocessor directives begin with #, and only white space characters may appear before a preprocessor directive on a line. 10.2 The #include Preprocessor Directive - The #include directive causes copy of a specified file to be included in place of the directive. The two forms of the #include directive are: //searches for header files and replaces this directive //with the entire contents of the header file here #include <header_file> - Or #include "header_file" e.g. #include <stdio.h> #include "myheader.h" - If the file name is enclosed in double quotes, the preprocessor searches in the same directory (local) as the source file being compiled for the file to be included, if not found then looks in the subdirectory associated with standard header files as specified using angle bracket. - This method is normally used to include user or programmer-defined header files.

  • Advanced Perl
    Advanced Perl Boston University Information Services & Technology Course Coordinator: Timothy Kohl Last Modified: 05/12/15 Outline • more on functions • references and anonymous variables • local vs. global variables • packages • modules • objects 1 Functions Functions are defined as follows: sub f{ # do something } and invoked within a script by &f(parameter list) or f(parameter list) parameters passed to a function arrive in the array @_ sub print_sum{ my ($a,$b)=@_; my $sum; $sum=$a+$b; print "The sum is $sum\n"; } And so, in the invocation $a = $_[0] = 2 print_sum(2,3); $b = $_[1] = 3 2 The directive my indicates that the variable is lexically scoped. That is, it is defined only for the duration of the given code block between { and } which is usually the body of the function anyway. * When this is done, one is assured that the variables so defined are local to the given function. We'll discuss the difference between local and global variables later. * with some exceptions which we'll discuss To return a value from a function, you can either use an explicit return statement or simply put the value to be returned as the last line of the function. Typically though, it’s better to use the return statement. Ex: sub sum{ my ($a,$b)=@_; my $sum; $sum=$a+$b; return $sum; } $s=sum(2,3); One can also return an array or associative array from a function. 3 References and Anonymous Variables In languages like C one has the notion of a pointer to a given data type, which can be used later on to read and manipulate the contents of the variable pointed to by the pointer.

  • Assembly Language Programming
    Experiment 3 Assembly Language Programming Every computer, no matter how simple or complex, has a microprocessor that manages the computer's arithmetical, logical and control activities. A computer program is a collection of numbers stored in memory in the form of ones and zeros. CPU reads these numbers one at a time, decodes them and perform the required action. We term these numbers as machine language. Although machine language instructions make perfect sense to computer but humans cannot comprehend them. A long time ago, someone came up with the idea that computer programs could be written using words instead of numbers and a new language of mnemonics was de- veloped and named as assembly language. An assembly language is a low-level programming language and there is a very strong (generally one-to-one) correspondence between the language and the architecture's machine code instructions. We know that computer cannot interpret assembly language instructions. A program should be developed that performs the task of translating the assembly language instructions to ma- chine language. A computer program that translates the source code written with mnemonics into the executable machine language instructions is called an assembler. The input of an assembler is a source code and its output is an executable object code. Assembly language programs are not portable because assembly language instructions are specific to a particular computer architecture. Similarly, a different assembler is required to make an object code for each platform. The ARM Architecture The ARM is a Reduced Instruction Set Computer(RISC) with a relatively simple implementation of a load/store architecture, i.e.

    Introduction to GPU Programming with CUDA and OpenACC Alabama Supercomputer Center 1 Alabama Research and Education Network Contents Topics § Why GPU chips and CUDA? § GPU chip architecture overview § CUDA programming § Queue system commands § Other GPU programming options § OpenACC programming § Comparing GPUs to other processors 2 What is a GPU chip? GPU § A Graphic Processing Unit (GPU) chips is an adaptation of the technology in a video rendering chip to be used as a math coprocessor. § The earliest graphic cards simply mapped memory bytes to screen pixels – i.e. the Apple ][ in 1980. § The next generation of graphics cards (1990s) had 2D rendering capabilities for rendering lines and shaded areas. § Graphics cards started accelerating 3D rendering with standards like OpenGL and DirectX in the early 2000s. § The most recent graphics cards have programmable processors, so that game physics can be offloaded from the main processor to the GPU. § A series of GPU chips sometimes called GPGPU (General Purpose GPU) have double precision capability so that they can be used as math coprocessors. 3 Why GPUs? GPU Comparison of peak theoretical GFLOPs and memory bandwidth for NVIDIA GPUs and Intel CPUs over the past few years. Graphs from the NVIDIA CUDA C Programming Guide 4.0. 4 CUDA Programming Language CUDA The GPU chips are massive multithreaded, manycore SIMD processors. SIMD stands for Single Instruction Multiple Data. Previously chips were programmed using standard graphics APIs (DirectX, OpenGL). CUDA, an extension of C, is the most popular GPU programming language. CUDA can also be called from a C++ program. The CUDA standard has no FORTRAN support, but Portland Group sells a third party CUDA FORTRAN.
