随着计算机科学技术的飞速发展，计算机技术被应用在了越来越广泛的领域，实现各种各样功能的计算机程序被大量地开发出来，应用在我们的生活、学习和工作当中。相应地，也产生了许多用以编写这些计算机程序的高级程序设计语言。程序编制者通过特定语言的编译器将自己编写的源程序翻译为特定机器上的目标程序，从而能够最终达到程序执行的目的。-With the rapid development of computer science, computer technology is used in an increasingly wide range of areas, to achieve various functions of the computer program was developed in large numbers, the application in our lives, learning and on the job. Accordingly, also produced a number of computer programs used in the preparation of these high-level programming language. Who through specific programming language compiler will translate your source code written for a specific target program on the machine, which can ultimately achieve the purpose of execution of the program.
