前言

PROGRAMMING LANGUAGE DESIGN IS A FASCINATING TOPIC. There are so many programmerswho think they can design a programming language better than one they are currentlyusing; and there are so many researchers who believe they can design a programming lan-guage better than any that are in current use. Their beliefs are often justified, but few oftheir designs ever leave the designer's bottom drawer. You will not find them representedin this book.Programming language design is a serious business. Small errors in a language design canbe conducive to large errors in an actual program written in the language, and even smallerrors in programs can have large and extremely costly consequences. The vulnerabilitiesof widely used software have repeatedly allowed attack by malware to cause billions ofdollars of damage to the world economy. The safety and security of programming lan-guages is a recurrent theme of this book.

《編程大師智慧》的主要特色在于它是多位編程語(yǔ)言創(chuàng)造者的獨(dú)家采訪，他們創(chuàng)造的這些編程語(yǔ)言極具歷史意義，對(duì)于當(dāng)下的信息社會(huì)產(chǎn)生了重大影響。從這部獨(dú)特的采訪集中，你將了解到某些特殊設(shè)計(jì)決定產(chǎn)生的過(guò)程，包括這些先行者當(dāng)時(shí)頭腦中的既定目標(biāo)、他們不得不做的折衷權(quán)衡，以及這些寶貴經(jīng)驗(yàn)至今對(duì)編程產(chǎn)生了怎樣的影響。    如果你對(duì)那些用遠(yuǎn)見(jiàn)卓識(shí)和努力工作造就計(jì)算機(jī)產(chǎn)業(yè)的人們感興趣的話，那么自然會(huì)發(fā)現(xiàn)《編程大師智慧》是一本令人著迷的好書。

章節(jié)摘錄

This is of course what we have for usual numeric types, such as ints, doubles, complexnumbers, and mathematical abstractions, such as vectors. This is a most useful notion,which C++ supports for built-in types and for any user-defined type for which we want it.This contrast to Java where built-in types such and char and int follow it, but user-definedtypes do not, and indeed cannot. As in Simula, all user-defined types in Java have refer-ence semantics. In C++, a programmer can support either, as the desired semantics of atype requires. C# （incompletely） follows C++ in supporting user-defined types with valuesemantics."General resource management" refers to the popular technique of having a resource （e.g.,a file handle or a lock） owned by an object. If that object is a scoped variable, the lifetimeof the variable puts a maximum limit on the time the resource is held. Typically, a con-structor acquires the resource and the destructor releases it. This is often called RAIIiResource Acquisition Is Initialization） and integrates beautifully with error handlingusing exceptions. Obviously, not every resource can be handled in this way, but manycan, and for those, resource management becomes implicit and efficient.
