Question 36 of 39 Question 36 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. In object-oriented programming, what is the relationship between objects and variables? In object-oriented programming, “object” is the term used to indicate any variable with an unspecified value. In object-oriented programming, once variables change value more than one time, they become known as objects.

Question 38 of 39 Question 38 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. An IT administrator is attempting to write a short program to fix a security issue that he has discovered. However, when he attempts to execute his new program, he receives the message that some of the class names he used are undefined, and the program does not run. What kind of language must he be using, and why? A low-level language; because it is incapable of running without all parts of the program being explicitly defined. A compiled language; because it requires that all parts of the program be defined before the program can run. A machine language; because otherwise the language translator program would be able to fill in any missing definitions.An interpreted language; because he cannot test it without the entire program being completely defined. Correct. Question 39 of 39 Question 39 This is not a form; we suggest that you use the browse mode and read all parts of the question carefully. What advantage does an interpreted language have compared to a compiled language? The final code of an interpreted language is much more efficient than that of a compiled language. An interpreted language allows for the testing of partially completed programs, speeding the code development process. Interpreted languages can be run by any compiler, regardless of what particular language the compiler was designed for. Interpreted languages work far more effectively with files, graphics, and security concerns than compiled languages do.
