Write a program to read four lines of upper case (i.e., all CAPITAL LETTERS) text input (no more than 72 characters per line) from the input file and print a vertical histogram that shows how many times each letter (but not blanks, digits, or punctuation) appears in the all-upper-case input. Format your output exactly as shown.
Microsoft .net IL 匯編語言程序設計指南.
To tell the truth, I don t think I had much choice in this matter. Let me explain. With Microsoft .NET technology taking the world by storm, with more and more information professionals getting involved, large numbers of books covering various aspects of this technology have started to arrive—and none too soon. Alas, virtually all of these books are dedicated to .NET-based programming in high-level languages and rapid application development (RAD) environments. No doubt this is extremely important, and I am sure all these books will have to be reprinted to satisfy the demand. But what about the plumbing?
This will sample all 8 A/D-channels.
The result will be send out via UART1 and can be seen within
any terminal-program (9600 Baud).
With each pressed key the next channel will be converted.
No interrupts are used.

EKF-SLAM Simulator
This version of the simulator uses global variables for
all large objects, such as the state covariance matrix.
While bad programming practice, it is a necessary evil
for MatLab efficiency, as MatLab has no facility to avoid
gratuitous memory allocation and copying when passing
(and modifying) variables between functions. With this
concession, effort has been made to keep the code as
clean and modular as possible.
ATViewer is a component for Delphi/C++Builder, which allows to view files of various types. There is no edit possibility, just quick view - so it s useful to implement "View file" feature in your Delphi/C++Builder application.
The following view modes are implemented:
Text, Binary, Hex, Unicode: all files, of unlimited size. Plain file dump is shown. Used ATBinHex component: only visible part of file is loaded into memory. Modes are suitable for huge files and files of unknown type.
RTF/UTF-8: RTF and UTF-8 encoded texts. File is shown using RichEdit control.
Image: all general image formats: BMP JPG ICO GIF PNG... File is shown using ATImageBox component.
Multimedia: all file types supported by MS Windows Media Player: AVI MPEG WMV MP3... File is shown using WMP ActiveX control.
Internet: all file types supported by MS Internet Explorer: HTML XML DOC XLS... File is shown using MSIE ActiveX control.
Plugins: all files supported by Total Commander Lister plugins.
simulates coin tossing. Let the program toss a coin each time the user chooses the “Toss Coin” menu option. Count the number of times each side of the coin appears. Display the results. The program should call a separate method flip that takes no arguments and returns false for tails and true for heads. [ Note: If the program realistically simulates coin tossing, each side of the coin should appear approximately half the time.]
Welcome to Beginning Algorithms, a step-by-step introduction to computing algorithms for the real world.
Developers use algorithms and data structures every day of their working lives. Having a good understanding
of these algorithms and knowledge of when to apply them is essential to producing software
that not only works correctly, but also performs efficiently.
This book aims to explain those algorithms and data structures most commonly encountered in day-today
software development, while remaining at all times practical, concise, and to the point, with little or
no verbiage to distract from the core concepts and examples.
Exuberant Ctags is a multilanguage reimplementation of the much-underused
ctags(1) program and is intended to be the mother of all ctags programs. It
generates indexes of source code definitions which are used by a number of
editors and tools. The motivation which drove the development of Exuberant
Ctags was the need for a ctags program which supported generation of tags
for all possible C language constructs (which no other ctags offers), and
because most were easily fooled by a number of preprocessor contructs.
