An indefinite loop is a loop that never stops. You can either increment or decrement the loop control variable. When one loop appears inside another is is … an indented loop. Forgetting to initialize and alter the loop control variable is a common mistake that programmers sometimes make. Every high-level comput...

The sorting process is usually reserved for a relatively large number of data items.The most popular computer coding schemes include ASCII, Numeric, and EBCDIC.You can make additional improvements to a bubble sort to reduce unnecessary comparisonsAn insertion sort is another name for a bubble sortTwo-dimensional arrays are never actually required in order to achieve a useful program

Methods in object-oriented programs use sequence, selection, and looping structures and make use of arraysIn addition to their attributes, class objects have methods associated with them; every object that is an instance of a class possesses different methodsWithin any object-oriented program, you continuously make requests to objects’ methods, often including arguments as part of those requests.Declaring a class does not create actual objectsClass diagrams are a type of Unified Modeling Langu...

With a selection structure, you perform an action or task, and then you perform the next action, in order. ANS: F PTS: 1 REF: 95 2. In a structured program, any structure can be nested within another structure. ANS: T PTS: 1 REF: 103 3. Because you may stack and nest structures while retaining overall structure, it might be difficult to determine whether a flowchart as a whole is structured. ANS: T PTS: 1 REF: 104 4. As a general rule, an eof question should always come immediately after an inpu...

TRUE/FALSE 1. You can invoke or call a method from another program or method. ANS: T PTS: 1 REF: 371 2. When methods must share data, you can pass the data into and return the data out of methods. ANS: T PTS: 1 REF: 373 3. A method could be called using any numeric value as an argument, whether it is a variable, a named constant, or a literal constant. ANS: T PTS: 1 REF: 378 4. Most programmers consciously make decisions about cohesiveness for each method they write. ANS: F PTS: 1 REF: 405 5. Pr...

Images and music are contained in binary filesWhen you copy data from RAM into a file on a storage device, you read to the fileThe keyboard and printer are the default input and output devices.Programmers usually use the word “write” to mean “produce hard copy outputTo write a program that produces a report of employees by department number, the records must be grouped by department number before you begin processing.

Methods in object-oriented programs use sequence, selection, and looping structures and make use of arrays. In addition to their attributes, class objects have methods associated with them; every obj ect that is an instance of a class possesses different methods. Within any object-oriented program, you continuously make requests to objects’ methods, often including arguments as part of those requests. Declaring a class does not create actual objects. Class diagrams are a type of Unified Modeli...

MIS 505 Final Exam Review 3 Chapter 8: Advanced Data Handling Concepts 1. The sorting process is usually reserved for a relatively large number of data items. 2. The most popular computer coding schemes include ASCII, Numeric, and EBCDIC. 3. You can make additional improvements to a bubble sort to reduce unnecessary comparisons. 4. An insertion sort is another name for a bubble sort. 5. Two-dimensional arrays are never actually required in order to achieve a useful program. 6. Some programming l...

Questions: Review 7 Every decision you make in a computer program involves evaluating a Boolean expression. In any Boolean expression, the two values compared can … either variables or constants. Any decision can … made using combinations of just two types of comparisons: equal and not equal. Most programming languages allow you to ask two or more questions in a single comparison. A short-circuit evaluation is where each part of an expression is evaluated only as far as necessary to determin...
