多数程序设计语言处理整数的能力时有限的,如C语言中,int类型数据范围是-32768-32767。实际问题的处理过程中往往涉及大整数的运算,如RSA加密算法要求至少64bit的整数,设计算法实现大整数的加减运算。-majority programming language processing integral to the limited capacity, such as C language, int data type is the scope -32768-32767. Practical problems of the treatment process often involves large integer arithmetic, such as the RSA encryption algorithm requires at least 64-bit integers, design algorithm large integer addition and subtraction operations.

使用c++编程语言,实现DES加密解密算法-Using c++ programming language, the realization of DES encryption and decryption algorithm
Date : 2025-12-19 Size : 10kb User : asdf

This book introduces standard C++ and the key programming and design techniques supported by C++. Standard C++ is a far more powerful and polished language than the version of C++ introduced by the first edition of this book. This book presents every major C++ language feature and the standard library. It is organized around language and library facilities.The primary aim of this book is to help the reader understand how the facilities offered by C++ support key programming techniques. The aim is to take the reader far beyond the point where he or she gets code running primarily by copying examples and emulating programming styles from other languages. Only a good understanding of the ideas behind the language facilities leads to mastery.

InsightThis a very different book on the C language! In an easy, conversational style, Peter van der Linden, of Sun s compiler and OS kernel group, presents dozens of astonishing examples drawn from practical experience, including: - Software that blew up the space probe to Venus - The C bug that shut down the entire AT&T phone system - C programmer job interview secrets - Why programmers can t tell Halloween from Christmas day - The C code for a complete BASIC interpreter Expert C Programming reveals the coding techniques used by the best C programmers. It relates C to other languages, and includes an introduction to C++ that can be understood by an programmer without weeks of mind-bending study. Covering both the IBM PC and UNIX systems, it is an entertaining and educational romp through C showing how experts really use it. Expert C Programming is a must read for anyone who wants to learn more about the implementation, practical use, and folklore of C.-InsightThis is a very different book on the C language!
