What Do You Call The Process Of Paying Attention To Important Properties While Ignoring Non Essential Details? - Fixanswer

A declaration of a variable is where a program says that it needs a variable. For our small programs, place declaration statements between the two braces of the main method. The declaration

gives a name and a data type for the variable

. It may also ask that a particular value be placed in the variable.

When an action is required if a condition is true but no action is needed if it is false you use a?

Which lets you focus on essential aspect of an application while ignoring details?

Explanation:

Encapsulation

allows us to focus on what something does without considering the complexities of how it works. Abstraction allows us to consider complex ideas while ignoring irrelevant detail that would confuse us.

Why do we use comments?

Comments are

text notes added to the program to provide explanatory information about the source code

. They are used in a programming language to document the program and remind programmers of what tricky things they just did with the code and also helps the later generation for understanding and maintenance of code.

What is another name for structured programming?

Structured programming (sometimes known as

modular programming

) enforces a logical structure on the program being written to make it more efficient and easier to understand and modify.

What are the three structures of structured programming?

Structured programming (SP) is a technique devised to improve the reliability and clarity of programs. In SP, control of program flow is restricted to three

structures, sequence, IF THEN ELSE, and DO WHILE

, or to a structure derivable from a combination of the basic three.

Why is it best to use only three programming structures?

Why is it best to use only three programming structures? ANS:•

Clarity—The number

-doubling program is a small program. As programs get bigger, they get more confusing if they’re not structured. Professionalism—All other programmers (and programming teachers you might encounter) expect your programs to be structured.

What is difference between variable declaration and definition?

Declaration Definition	A variable or a function can be declared any number of times A variable or a function can be defined only once

What goes first when declaring a variable?

Rationale: It’s best to declare variables when you first use them to ensure that they are always initialized to some valid value and that their intended use is always apparent.

Which loop is guaranteed to execute at least one time?

while loop

is guaranteed to execute at least one time.

What will a computer do if the if condition turns out to be true?

If the condition is true,

only the code next to then will run and all the code next to else will be ignored

. If your condition is false, the code next to then will be ignored and the code next to if will run.

When a condition in an if the statement is true?

In an if…else statement, if the code in the parenthesis of the if statement is true,

the code inside its brackets is executed

. But if the statement inside the parenthesis is false, all the code within the else statement’s brackets is executed instead.
