高清電子書-C++ Primer Plus, 第6版英文版 1438頁Learning C++ is an adventure of discovery, particularly because the language accommodates several programming paradigms, including object-oriented programming,
generic programming, and the traditional procedural programming.The fifth edition of
this book described the language as set forth in the ISO C++ standards, informally
known as C++99 and C++03, or, sometimes as C++99/03. (The 2003 version was
largely a technical correction to the 1999 standard and didn’t add any new features.)
Since then, C++ continues to evolve.As this book is written, the international C++
Standards Committee has just approved a new version of the standard.This standard had
the informal name of C++0x while in development, and now it will be known as
C++11. Most contemporary compilers support C++99/03 quite well, and most of the
examples in this book comply with that standard. But many features of the new standard
already have appeared in some implementations, and this edition of C++ Primer Plus
explores these new features.
C++ Primer Plus discusses the basic C language and presents C++ features, making
this book self-contained. It presents C++ fundamentals and illustrates them with short,
to-the-point programs that are easy to copy and experiment with.You learn about
input/output (I/O), how to make programs perform repetitive tasks and make choices,
the many ways to handle data, and how to use functions.You learn about the many
features C++ has added to C, including the followi

本系統(tǒng)采用電動機(jī)電樞供電回路串接采樣電阻的方式來實(shí)現(xiàn)對小型直流有刷電動機(jī)的轉(zhuǎn)速測量。該系統(tǒng)主要由二階低通濾波電路,小信號放大電路、單片機(jī)測量顯示電路、開關(guān)穩(wěn)壓電源電路等組成。同時自制電機(jī)測速裝置,用高頻磁環(huán)作為載體,用線圈繞制磁環(huán),利用電磁感應(yīng)原理檢測電機(jī)運(yùn)行時的漏磁,將變化的磁場信號轉(zhuǎn)化為磁環(huán)上的感應(yīng)電流。用信號處理單元電路將微弱電信號轉(zhuǎn)化為脈沖信號,送由單片機(jī)檢測,從而達(dá)到準(zhǔn)確測量電機(jī)的速度的要求。In this system, the sampling resistance of armature power supply circuit is connected in series to measure the speed of small DC brush motor. The system is mainly composed of second-order low-pass filter circuit, small signal amplifier circuit, single-chip measurement and display circuit, switching regulated power supply circuit and so on. At the same time, the self-made motor speed measuring device uses high frequency magnetic ring as the carrier, coil winding magnetic ring, and electromagnetic induction principle to detect the leakage of magnetic field during the operation of the motor, which converts the changed magnetic field signal into the induced current on the magnetic ring. The weak electric signal is transformed into pulse signal by signal processing unit circuit, which is sent to single chip computer for detection, so as to meet the requirement of accurate measurement of motor speed.
