Question 7

grouping together a group of instructions in order to reuse the group more than once is to make

Accepted Answer

a function

Question 8

To add more information to a standard function to make it more customizable is called a

Accepted Answer

parameter

Question 9

Extensive defining and writing of functions allow the programmer

Accepted Answer

'hide' lines of detailed code, not to have to solve the problem again, to invoke the new function by name whenever required, to solve a problem to a well-defined portion of the task

Question 10

When writing functions in computer programs they allow the programmer to

Accepted Answer

put code in more logical chunks, create a form of abstraction, focus on what something does, rather than how it does it., make their code clearer or more concise

Question 15

Abstractions allow you to

Accepted Answer

focus on relevant concepts,, reason about problems at a higher level., hide details to help you manage complexity, simplify something more complex

Question 16

Accepted Answer

makes the programming problem easier

Question 17

Which is the following is true. when code is considered efficient, it could

Accepted Answer

hinge on the ability to reuse code within your own code., mean the number of lines of code is optimum, mean the total number of primitive operations, be about the speed & clarity in which the program is written

Question 18

The efficiency of a computer program can be measured by

Accepted Answer

How much memory the program takes to run, How long the program takes to run, How many lines of code are in the program, How big the tea of programmers are to create the code

Question 19

How should I prepare for the ITS exam
