The second volume in the Write Great Code series supplies the critical information that today s computer science students don t often get from college and university courses: How to carefully choose their high-level language statements to produce efficient code. Write Great Code, Volume 2: Thinking Low-Level, Writing High-Level, teaches software engineers how compilers translate high-level language statements and data structures into machine code. Armed with this knowledge, a software engineer can make an informed choice concerning the use of those high-level structures to help the compiler produce far better machine code--all without having to give up the productivity and portability benefits of using a high-level language

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute. Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets a systematic way of dealing with datasets having components of non-uniform length tools for fine-tuning figures using compact, straightforward statements and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.

Run the SQL script given to you to create a Library database. Note that each row in the Book table denotes a book copy. Thus, if the library carries three copies of the title "DBMS", there will be three rows in the Book table, one for each copy. Write the SQL statements to do the following against the database

在C++中open一個output file有兩種方式，一種是使用member function open( )，另外一種是使用constructor給予檔案名稱和open mode。今若欲open一個名為client.dat的output file，試分別寫出該兩種方式open此檔案的statements.(包括include header file，物件的宣告，open指令等)

Need to make sense of the many changes to Visual Basic for the new .NET platform? VB .NET Language in a Nutshell introduces the important aspects of the language and explains the .NET framework. An alphabetical reference covers the functions, statements, directives, objects, and object members that make up the VB .NET language. To ease the transition, each language element includes a "VB .NET/VB 6 Differences" section.

how to add arrays * Use of const (constant) values. * Creation of vectors. * Passing vectors as function arguments. * Reading from files of unknown size (monitoring istream status). * Repetitive structures (while and for loops). * The increment operators (++). * Selection structures (if-else statements). * Use of the .size, .empty, .begin, .insert, .erase, .resize, .clear and .swap vector class member functions.
