Answer and Explanation:
The ways in which a layered pattern make use of encapsulation and abstraction are as follows:
- This framework lays its focus mainly on the bundling of related functionalities inside an application into different layer that are vertically stacked over one another.
- Functionality in between each layer is related by common function or role.
- Communication in between the layers is clear and exact and is coupled loosely.
- Providing a layered structure to the application indirectly supports its maintainability and flexibility.
Encapsulation:
Since, features like data type, properties, methods or implementation while designing are not exposed at the boundary of the layer thus No assumptions are required for these features.
Abstraction:
The layered framework abstracts the entire system's view and provides adequate details for better understanding of the roles of each layer individually and the relation that exist between these layers.
Let's solve this together.
To make a search term more accurate, you must keep it simple and you must be able to use more specific terms. The more specific you are with what you are asking the engine about, the more friendlier it will respond.
The answer is Option B. I hope this answer helped you!
Answer:
None of those answers is correct because E[1101] is index out of range.
Answer:
sed '/march/{d;}' birthdays.txt > result
.txt
Explanation:
sed syntax is basically:
<em>sed '/expression/{command;command;...;}' inputfile > outputfile</em>
- First, for the expression part, we use /march/ to match all lines containing that string.
- Then for the command part, we only use {d} command to delete every matching line found.
- The third part contains the input file to process, I have named it birthdays.txt, but it could have been any other file needed.
- Finally "> result
.txt" makes the script output to be saved into a file named result.txt
