Exercises

一、根据课文内容，判断正误

1）Programs can be characterized as interactive or batch and a command interpreter or a Web browser is an example of an interactive program.

2）Structured programming frequently employs a bottom-up design model，in which developers map out separate subsections into the overall program structure.

3）Almost all languages can use structured programming techniques to avoid common pitfalls of unstructured languages.

4）A compiler is a special program that processes statements written in a particular program-ming language and turns them into machine language or“code”that a computer’s processor uses.

5）A compiler works with 3GL and higher-level languages and on programs written using a pro-cessor’s assembler language.

6）Interpreted programs generally don’t run as fast as compiled programs.

7）An interpreter translates high-level instructions into machine language while a compiler translates high-level instructions directly into an intermediate form.

8）C，FORTRAN，or Pascal are considered high-level because they are closer to human lan-guages and further from machine languages.

9）A scripting language is a low-level programming language that is interpreted by another pro-gram at runtime.

10）Scripting languages can be embedded within HTML.

二、把下列句子翻译为中文

1）A virus is a self-replicating computer program that spreads itself into other programs，often without the knowledge or consent of the computer owner.

2）Google Maps is an interactive program for most smart phones that offers tons of features so you will never have to be lost again.

3）Batch and utility programs typically deal with large amounts of data，often processing the data in a sequential manner.

4）Structured Programming utilizes sequential，selective，and repetitive structures to design programs.

5）C language is a general-purpose programming language that provides code efficiency，ele-ments of structured programming，and a rich set of operators.

6）By compiling before the program executes，the AOT compiler must be conservative about classes，fields，and methods referenced by the code it compiles.

7）If you step through the code you will see that the compiler is very flexible when it creates these methods.

8）Interpreted programs are much slower tnan compiled or assembled ones because a statement must be translated with each execution.

9）In many scripting languages，you don’t have to worry about how memory is managed，but that doesn’t make memory management any less important.

10）The drawback of scripting languages has always been performance.However，scripting lan-guages have distinct advantages，too.
