Incluye información técnica, reseñas detalladas, consejos sobre habilidades y experiencias de productos, etc. Tiene formatos de contenido gráfico, de video e infomercial y cubre las principales plataformas de nuevos medios.
- Which of the following are benefits of procedural abstraction? Select two answers. Procedural abstraction prevents programmers from accidentally using the intellectual property of other programmers. Procedural abstraction eliminates the need for programmers to document their code. Procedural abstraction makes it easier for people to read computer programs. square Procedural abstraction provides an opportunity to give a name to a block of code that describes the purpose of the code block.
- Which of the following is a benefit of using a simulation instead of an experiment to make a prediction? Select two answers. A simulation allows investigation of a phenomenon without the real-world limitations on time, safety, or budget. A simulation can be used to model real-world events that are impractical for experiments. A simulation always produces the same output so its results can be verified. A simulation produces results that are more accurate than experimental results.
- A programmer has a need to round many numeric values to the nearest integer. Which of the following best explains the benefit of using a list as a data abstraction in this situation? A Keeping the numeric values in a list makes it easier to round a number to the nearest integer. B Keeping the numeric values in a list makes it easier to apply the same computation to every data element C Keeping the numeric values in a list makes it easier to prevent a program from unintentionally changing the value of a variable. D Keeping the numeric values in a list makes it easier to prevent a program from attempting to access an index beyend the length of the list
- 19 Which of the following is a benefit of using a list as a data abstraction in a program? A Lists often allow their size to be easily updated to hold as many data values as needed. B Lists convert all elements to strings so that they can be inspected character-by-character. C Lists prevent duplicate data values from appearing in the list. D Lists are used to store all input data so that there is a running record of all user input. Mark for Review
