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.

簡單的floyd運用 第一行輸入一個整數(shù)C。C是測試的情況(0< C <=30).第二行一個正整數(shù)N( 0< N <=100),表示道路的總數(shù).緊接N行,每一行包含兩個字符串, Si,,Ti,和一個整數(shù)Di,代表從Si到Ti的距離(0<= Di <=150)。最后一行有兩個字符串,S 和 T,你得找出從S 到 T的最短的距離。地名是不超過120個小寫字符的串(從‘a(chǎn)’到‘z’)。假設(shè)這里最多有100條直接連通兩個地方的路。 Output 輸出包含C行,每一行對一種測試情況。對每一種測試情況,輸出包含一個整數(shù),假如S 到 T存在一條最短的路,輸出從S到T的最短距離,否則輸出“-1”.

C++讀取Excel AppWizard uses "TODO:" to indicate parts of the source code you should add to or customize. If your application uses MFC in a shared DLL, and your application is in a language other than the operating system s current language, you will need to copy the corresponding localized resources MFC42XXX.DLL from the Microsoft Visual C++ CD-ROM onto the system or system32 directory, and rename it to be MFCLOC.DLL. ("XXX" stands for the language abbreviation. For example, MFC42DEU.DLL contains resources translated to German.) If you don t do this, some of the UI elements of your application will remain in the language of the operating system.
