The term“ （） program”means a program written in high-level language． A: compiler B: executable C: source D: object

The program that a computer can execute directly is ( ) A: source program B: target program C: assembler D: executable program

一个文件的权限是“rw-rw-r--”，这个文件的所有者的权限是（）。 A: read-only B: read-write C: write-only D: executable

A(n) ( ) translates all the source code of a program written in a high-level language into object code prior to the execution of the program. While a(n) ( ) program is translated into executable form and executed one statement at a time rather than being translated completely before execution. A: assembler B: editor C: programmer D: compiler E: interpreter

In the following description, which one is wrong? ( ). A: The executable program of C language is composed of a series of machine instructions B: The source program written in C language can not run directly on the computer C: The compiled binary object program needs to be connected to run D: The. exe file generated by C source program cannot be run on the machine without C language integrated development environment installed

.NET应用程序的编译过程如下图所示。[img=437x77]17de8eb7df07593.png[/img]以下关于.NET应用程序的编译过程的描述中，哪些是正确的？ A: .NET应用程序编译过程中的源文件是指用C B: 、VB.NET等.NET兼容语言编写的文本文件，称为源程序文件或.NET应用程序文件 C: 程序集可以是可执行文件(executable)，也可以是动态链接库文件(DLL)，其代码不是本地机的机器指令，而是CIL(Common Intermediate Language，公共中间语言)代码 D: 如果把英语看成公共中间语言，用中文写了一篇文章(源文件)，先由一个机构(编译器)译成一篇英语文章(程序集)。程序集可以在CLR上运行，由CLR再翻译为本地机的机器指令代码在本地机执行。这个过程相当于，用中间语言译成的英文文章到了德国(类似本地机)，就从英文译成德文给德国人看，到了法国则译成法文给法国人看。这个翻译工作由JVM的JIT(just-in-time，即时)编译器完成 E: 运行期间，CLR检查程序集的安全特征，分配内存空间，发送程序集的可执行代码到JIT并编译为本地机器指令代码。这种代码可以在本地机运行
