C++, although a marvelous language, isn t perfect. Matthew Wilson has been working with it for over a decade, and during that time he has found inherent limitations that require skillful workarounds. In this book, he doesn t just tell you what s wrong with C++, but offers practical techniques and tools for writing code that s more robust, flexible, efficient, and maintainable. He shows you how to tame C++ s complexity, cut through its vast array of paradigms, take back control over your code--and get far better results

圖像處理,利用bilt 函數 Description: This example shows how to edit (cut,paste,copy) a selection of a bitmap using BitBlt function just like Microsoft Photo Editor does. It s really EASY! Take a look to the sample if you don t believe me and don t forget to VOTE FOR ME! Note: comments are in italian...i hadn t enough time to translate them all. Sorry..(VOTE!)

分治法解決最近對問題 畫一條垂直線x=c,把這些給定點分為兩個包含n/2個點的子集S1和S2,使得n/2個點位于直線的左側或直線上,另外n/2個點位于直線的右側或直線上;遵循分治法的思想,遞歸地求出左子集S1和右子集S2中的最近對,分別為d1與d2;之后d=min{d1,d2}。合并過程:在以垂線x=c為對稱軸,2d為寬度的區域內求最近兩個點的距離,記為d3;求D=min{d,d3};

The market for miniature computer programming is exploding. C++ Footprint and Performance Optimization supplies programmers the knowledge they need to write code for the increasing number of hand-held devices, wearable computers, and intelligent appliances. This book gives readers valuable knowledge and programming techniques that are not currently part of traditional programming training. In the world of C++ programming, all other things being equal, programs that are smaller and faster are better. C++ Footprint and Performance Optimization contains case studies and sample code to give readers concrete examples and proven solutions to problems that don t have cut and paste solutions.

假設在一個ad hoc網絡中,移動節點的發射功率PTx總是恒定的。要發送數據的移動節點總是先監聽信道,測量接收到的信號功率X,其中X= I + N, I為接收到的干擾,N是噪聲。移動節點只有在X<INThre時,才可以發射。式中,INThre為背景噪聲門限。 在仿真中,我們規定每個移動節點的發射功率是常數,PTx = 1W;接收節點接收機的靈敏度Smin = -80 dBm;信號質量 min = 2 dB;系統的背景噪聲門限INThre = 1.2e-10。
